Can't send mail on other networks

We have been touring the country for two months now and find we often can't send mail (using Mail) on wireless networks in hotels and it happens when we are visiting friends as well. We can always receive mail, however. It's frustrating as we're keeping friends and family posted on our trip's progress. Any ideas??? We can send e-mail through our .mac account on the Apple web site but sending photos doesn't work as well.
Some hotel's systems work just fine.

Hello Frederick.
Most, if not all ISPs now block the use of SMTP servers that are outside of their network (or not provided by the ISP) on Port 25 which is the standard port used by SMTP servers.
Some ISPs allow the use of an authenticated SMTP server only (such as the .Mac SMTP server) on Port 25 but some block its use regardless.
These restrictions are in place as part of an overall effort to prevent spam emanating from the ISP's domain.
Some free wireless networks (at hotels) will allow using an SMTP server that is outside of their network on Port 25 if the SMTP server is not authenticated (and why is a good question if so) and in that situation, selecting None for SMTP authentication should work.
Basically, you need to check with the hotel or the hotel's internet service provider regarding their required settings for using an SMTP server that is outside of their network.
When visiting friends and connecting to the internet via their ISP, you can try the following:
Go to Mail > Preferences > Accounts and under the Account Information tab for your .Mac account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
If this doesn't allow you to send mail with your .Mac account and SMTP server, you can try entering and using the SMTP server provided by your friend's ISP to send mail with your .Mac account which is invisible to all recipients.
When accessing free wireless networks at hotels, you can try using 587 for the Server Port for the .Mac SMTP server but as previously provided, you need to check with the hotel or the hotel's ISP to determine the required settings for using an SMTP server that is outside of their network.
If using 587 for the SMTP Server Port works, you should be able to keep this setting for the .Mac SMTP server when returning home. I use Port 587 for the .Mac SMTP server when connected to my ISP at home and I've also used it successfully when connected to a friend's wireless network via a different ISP.

Mail can't send mail on home network

I am trying to help a friend who wants to move from Entourage to Mail. He has a MacBook Pro with 10.6.4 installed and his company uses Exchange 2003. He is moving to Mail due to serious calendar and contact syncing issues through Entourage and his iPhone/iCal/Address Book.
I have setup his Mail account to use IMAP with the Exchange Server. He can receive mail this way, but he cannot send it. Actually he can only send mail when he is at work on his company's network. I have turned off SSL and authentication is through Username and Password.
Funny thing is that Entourage can send and receive mail anywhere he has a connection, but Mail cannot. His company's IT department says that the settings I have in place should work.
How can I further troubleshoot this problem? Is it a server problem? I know 10.6's Mail doesn't support Exchange 2003, but I am not looking for full integration of exchange services.

You may be SOL as you need an SMTP server to send mail and the IT folks may not have it set up. You need a proper SMTP relay to send the mail, period. It doesn't matter what it's called, though convention usually has it set to smtp.example.com. mail.example.com would more often be the address for IMAP or POP connections.
Regarding the inability to send mail from an external network, this is the same problem: You still need an SMTP server to send emails. It's just that the SMTP server on the external network is likely different than the corporate SMTP server. What external network is it, and what is the SMTP server they have set up for machines within their network? Note that many networks don't enable outbound SMTP for random clients due to SPAM reasons.

Hi,
Are you using Outlook clients? Is this problem reproduceable when sending on Web?
I've seen some of this issues were caused by the wrong time/date or timezone settings, please make sure you have configured the time, date and timezone correctly on your PCs.
There are some other possible causes for this issue, if your email was not accepted, maybe the message in question may contain characteristics that the targeted server will not accept for policy reasons.
For example, it is against some mails' policy to accept messages with malicious content or manipulated header information, such as:
A falsified origination point.
An altered sending date.
A forged email address.
If you're the administrator for the mail server in question, we ask that you review outgoing messages for potentially objectionable content or practices.

Can no longer send mail from other apps

Problem:
If I go into any app (other than Mail) and try to send a message (via email) and I either get nothing or some apps will say that "Mail needs to be configured in order to do this." After doing a restore on my iPod touch (4th Gen., running the latest iOS5) I had only configured a few accounts under "Mail, Contacts, Calenddars", and *was* able to send mail from other apps just fine. Now that I have 13 accounts I cannot; not only is Mail configured and working fine (by itself,) but I now only have one account with "Mail" activated, and it is indeed set as the "default account" in Settings anyhow. This is frustrating since some apps depend on email to let me export its data but is also a nuisance since it makes it more difficult for me to share content with others.
Has anyone encountered this bug and/or have a tip?

It is possible the Evil Starbucks empire has blocked SMTP sending as an antispam measure. You would need to log in to your email server using the smtpauth protocol. For example, Earthlink has an smtpauth.earthlink.net server for secure sending, which I was able to use sending from any public AP. Possibly T-Mobile has a similar authorized server.
But nowadays I just use Gmail, they make it easy and reliable to send from anywhere because they use a custom smtp port. Yeah, Gmail solved a multitude of problems with mobile sending.

I can not send mail when at school. Please help

I can not send mail when at school. Please help

What is the email provider? If it is from your home Internet service provider, they usually block sending when not on their network. If this is the case, see if you can log into the smtp server with username and password. If they allow that, you can enter that in the email account settings.

Can Not Send Mail- what's going on?

Can download mail but can not send mail. With parallels on and xp pro I can easily set up outlook to send and receive mail. But no! The great Apple which is supposed to be easy can not send an email with the same settings. So, back to Windows to do what should be easy on a mac. I think that perhaps the new Safari or something messed this up.

If you'd like to approach the problem as something you don't understand, and also something that can be fixed, then you'll probably be able to set up your email account.
You say you have emails in the Outbox. I'd move them to another folder you create or delete them. In past experience, emails contain header information that includes mail server information, and sometimes they will never send (especially with Outlook Express), even if you get the account to work. You can try sending them again, once you get the account working.
Next, you need to make sure that you are sending the emails from a machine that is connected directly to RoadRunner's network. They may not work as a relay if you connect from another ISP. It's a port 25 problem that is common these days.
Now for the problem. If you are receiving emails properly, then the POP server information is correct. The mail program is designed to set up to some default settings that work with many servers, and during the process it will try to validate the settings you supply. This can take awhile, and can come up with a failure, due to a wrong assumption. Your email program is assuming that the email server requires authentication. This has been a problem with the RoadRunner system for years. Apparently, some windows email clients do not work the same way, go figure. They seem to have their own problems.
Many people have reported successfully setting up an account with RoadRunner, after first making sure they have the right SMTP server address. It can be different for different parts of the country.
After the email account is set up, and is failing to work, people go into the Mail/Preferences/Accounts/Account Information/Outgoing Mail SMTP Server - Click on the dropdown button - Choose "Edit Server List" - Advanced - Change Authentication to "None"
Here is a related thread with stories of success with RoadRunner: http://discussions.apple.com/thread.jspa?messageID=9128382&
After the changes, I'd quit and relaunch Mail. Not required, but good troubleshooting practice. Since there are no emails in the Outgoing Mailbox, create a short message and try to send.
I have different problems with different companies for both Mac's and Windows machines. The ISP always blames the OS, especially Leopard and Vista (since they work with more intelligent/advanced (maybe) settings. Besides the Authentication issue that pops up with some servers, there's also the occasional SSL variation and/or login name (sometimes it's the first part of the email address before the @ and sometimes it's the entire email address). Some ISP's block port 25, some do not. All of these settings can vary with each ISP, and can change on a whim (especially the port 25 problem), with working accounts going dark because of security changes at the ISP. Telephone Tech support at the ISP is often unaware of any changes in their system because they are not in the IT loop at the company and some will just go into "idiot" mode when you mention Macintosh. The first level support people are using a script on the phone, and their job is to make you go away...
I'm afraid the Great Apple, as you referred to them, is not able or hasn't focused on the ability to automatically set up accounts with every ISP. They appear to have made some assumptions that work with most servers. Who know's, next month the settings or assumptions may work, or Apple may update their setup script to make allowances specific to Time Warner, but since this has been a problem for over 3 years, I wouldn't hold my breath.
Google: leopard mail roadrunner problem = about 96,000 hits of all sorts.
Google: vista email roadrunner problem = about 1,410,000 hits of all sorts.
Google: windows xp email roadrunner problem = 243,000 hits of all sorts.
Looks like Apple's getting it's market share of problems with RoadRunner and Time Warner
My own local DSL is from a company named Centurytel. They are on their 4th email server setup in the last 5 years, and have finally contracted it out to a 3rd party company to administer. I just tell all of my clients to get a Gmail account and get over it. Let's see, a multi-billion dollar company who's reputation and income is based on service... free with 7GB storage, Webmail, POP and IMAP access, specific support for all major mail programs including Apple Mail, and alternate ports that get around ISP blocking. It seems that once you enable POP or Imap access in the webmail settings menu, Apple Mail and Vista seem to know the proper settings to use.
I'd setup the free Gmail account that will work with any ISP you use, before you get really attached to an email account with an ISP that could change as often as competitor's marketing allows. Also, my iPhone supports Gmail out of the box

Can't send mail when using mobile broadband

Hi
I am getting quite frustrated as I can't send mail when using my mobile broadband modem! I can receive mail, and surf the internet etc, but mail just wont send!(i get the usual cannot send try later/resend options). I thought this might be an issue with my mobile broadband but have recently reinstalled it. When at home on a wireless network I have no such issues.
Any help appreciated

I am not using a SMTP it is a Pop3 domain name account from freeparking and uses mail.'NAME'.com for incoming and outgoing mail!
Even though your e-mail service uses the same URL for POP3 and SMTP servers, in the software sense you actually do have separate POP3 and SMTP servers, although they may be hosted on the same machine, or the requests are routed via some "smoke and mirrors" to the right host.
It is not related to my ISP at home, which is Virgin media. My mobile broadband provider is 3. I was thinking it might be that I need to change the port settings in mail when using my mobile modem, but don't know what to change them too(or how to do it!) or configure the modem differently but again not sure what to do there!
Check with the freeparking online help to see if it supports port 587 or some such.
Also try Mail's "Connection Doctor" (under the Window menu) when you're away from home to see if that shows anything useful.
Since you can send e-mail from that SMTP server when you're at home but not when you're using your mobile broadband, I think one of two possibilities is likely: (a) Your mobile broadband provider is blocking your attempts to access the freeparking SMTP server and/or port. (b) The freeparking SMPT server for some reason doesn't like being communicated with via your mobile broadband provider. I'd check with each of them to explore these options.
Does your mobile broadband provider have an SMTP server that you can use instead of the freeparking one?
My modem(Huawei E220) is not particularly Mac friendly as it is, and I believe Mail can be quite sensitive when servers don't respond immediately?
Yes. Mail seems to have a fixed time-out value for server responses.

HELP: Cannot send mail when off network??

Hi we have set up the mail server on our Leopard server to host mail for our domain, we can successfully recieve and send mail when clients on on our internal network, and when off network can send as well. But when a client is not on the internal network (e.g. StarBucks or at home), they can not send mail using our server, even when on VPN. We have selected to use authentication, and the connection doctor in mail shows it is able to log in and connect with the server. any ideas?

I see it's been a month with no on-line response to your problem from Apple or anybody. That may indicate there isn't one that works 100%. I am having the exact same problem with all of the same companies. Add to it that I cannot get e-mail on my PC at home/office when the I-phone is turned on. I too have been in contact numerous times with Charter and Verizon, and have received zero return phone calls from either when promised. It seems that many people have these problems, but so far nobody can fix them? And I paid for this phone? I never thought I'd be at a point where I would consider returning to my Blackberry.

Can't send mail since 10.4.6 update

Since updating my OS to 10.4.6 I can't send mail. I can receive mail and I can browse online. But mail will not go out. I've verified all the Outgoing Mail Server info SEVERAL times and have had no luck. I've enabled Entourage to handle mail instead of MacMail and it won't work either. Totally stumped.
Same thing has happened on my iBook G4 laptop by the way. I'm convinced that the update has something to do with this.

INTERNET CONNECTION LOST
so... since the 10.4.6 update once my computers fall asleep the connection to my wireless router is lost. (mail seems to be working ok, when i have an internet connection...)
I have tried multiple things to fix this. Thus far the only solution seems to be resetting the router to use connect back to the internet. Once this is done the internet connection works fine, until lost or the computers go to sleep. When i wake the computer i have to do it all over again... and on top of it the post link is missing on all the pages!!! so i am replying here.
So this time I have rebooted to my external drive with the previous version (10.4.5) to see if indeed it is the 10.4.6 update that seems to have hosed this connection somehow.
HELP please, this is terrible annoying. Is anyone else experiencing this?
thank you.

Can't send mail on iOS 5 devices with iCloud

A long time ago I signed up for a .Mac trial to use that address with iChat. The trial expired, and, as expected, the address continued to work with iChat, though it no longer functioned as an email address. It then came to be my Apple ID. Now, having set that Apple ID up for use with iCloud, my iOS devicess are having trouble sending, and only sending email from my iCloud address. The reason is this: I logged into <username>@mac.com for iCloud (as that's my Apple ID), and everything set up right except the mail address that iOS Mail thinks I have. It thinks the mail address for the iCloud account is <username>@mac.com. When I send mail to <username>@me.com, my iOS devices get it just fine, but when I try to send mail back, it tries to send it from the @mac.com address, and therefore fails as that is not a valid email address.
I've tried to go into the settings and change the email address that it uses for iCLoud, but with no luck. I see a place to change it, but it is grayed out and won't let me select it and bring up a keyboard to change it.
Is there any way to tell it that it assumed the wrong email address for my iCloud? Or is there no way to send iCloud email from my iOS devices?
Thanks in advance!
P.S. I can send mail via iCloud from the web app and from Apple Mail (OS X Lion), but not from iOS devices because of this glitch. I can also send mail from iOS devices using other email accounts (Gmail, Yahoo).

I found a work around that works. Got to Settings...Icloud....account......advanced....outgoing mail server.....
Add an "other" server.
Host Name p01-smtp.mail.me.com
Put in your me.com email address as username and your Apple ID password
SSL is on
Authentication is password
Server port 587
This worked for me.....I will use this until the bug is fixed. (you may need to use p02, p03 etc) Don't make this server your primary. Leave it in "on" status in the other category.
Good luck

Can't send mail... after 4 months of using it

I'm stumped... help me out please.
When i send a mail out, this message pops up, "Error : This Message could not be delivered and will remain in your Outbox until it can be delivered. Sending the message content to the server failed."
So it's still in my mailbox. But then, it shows up in my gmail account and on my blackberry as a sent mail, but the receiver never gets it. Also, i can still send mail from both my blackberry and gmail.com... just not from Apple Mail.
What's going on?

Sometimes an ISP provider blocks one of your incoming
Mail ports and "won't notify you". ( Why? probably it's their protection software )
In my case Comcast blocked my Port 25 and my Outgoing kept bouncing.
Incoming was fine.
Make sure when you change your Port to 587,
You also check "ON" the Secure Sockets Layer box right underneath,
Then change Authentication: to Password
Then enter your name and password
and click OK.
The reps at most of the providers
are useless and won't tell you
the second part of the solution.
It took me 2 days and 4 reps
at Comcast to find this out
and 10 hours of trying to
clean my Mac...
which they will always
blame.
Best of Luck, Tom

Receiving mail, but can't send mail with attachments?

Hello,
I can't send mails anymore, I have been able to send some without any attachments (i.e. reply doesn't work as it automatically attaches the original text). This started 3 days ago. Also, my mail doesn't seem to recognize powerpoint and word docs., but I a know the people who have send me such files do not have VISTA. When I choose "open with" then it works. So I have 2 problems, one being moe urgent then the other.
1) can't send mail with attachments
2) .doc (word), .pps (powerpoint)attachments are not always recognized.
thank you all!!!

Try going into Settings > Mail, Contacts, Calendars > select the account > account name , tap on SMTP (under the 'Outgoing Mail Server' heading) and then tap on your Primary Server and try entering your email account and password and see if it then works

Can't Send MAIL..... again

hey...
can;t send mail..
10.4.10 on a macbook..
can send mail on my .MAC account, but my MAIL 2.0 is no good. it used to work fine...
i travel for a living, could the different log-on places have something to do with it.?
tried all the fixes on the Apple help site, no avail.
using port 587, removed and re-entered account, internet connection is fine...
want to use MAIL to send pix from my iPhoto's...
also, anyone know how to change the name in my account? somehow the spelling of my name is wrong, and every email i send says from 'blank' and it is wrong. looked at every piece of account info and they are all correct. where is the info for FROM: in an email stored...
cheers..!!!
ian

I'm having the same problem. I moved to a different apartment. I think my situation is this; my Mail says home and has my .mac account email address listed. My .mac account says .mac and has my .mac email address listed.
I've tried to change the Mail "home" so it doesn't say ,mac, but I haven't figured out how and when I change the email and server settings it tell me that it is an invalid directory.
So it's a circular puzzle and I can't seem to get out.
Is this your problem too? If not, do you know how to fix this one?

Can't send mail when connected to vpn

I'm hooked up with a private vpn service using OpenVpn. Everything works beautifully -- except that I can't send mail (receiving is no problem) because the SMTP ports offered through Mail 4.5 (ports 25, 465, 587) are blocked by many VPN providers as an anti-spam measure. I can't use port 993 with SSL because I live in Monaco, which has one ISP -- and it does not provide or support secure email (which is one of the reasons I want the VPN).
Is there another port I can select for SMTP, or some configuration tricks I'm missing? Thanks...:)

Hello Brian,
Basically this is the VPN group:
crypto isakmp client configuration group open
key (something)
dns 192.168.1.1 8.8.8.8
domain something.com
pool SDM_POOL_1
save-password
backup-gateway 192.168.1.1
max-users 5
netmask 255.255.255.0
banner ^Cyou have connected to the vpn-ings!. well done! ^
I see that you are doing tunnel all, and you are not split tunneling on this configuration, what you can do is to use split tunnel, under this configuration as follow:
ip access-list extended SPLIT_TUNNEL
permit ip XXXXX XXXXX 192.168.1.0 0.0.0.255
XXXXX --> are the inside subnets
Then under this:
crypto isakmp client configuration group open
acl SPLIT_TUNNEL
This will allow you to have access to the internal subnets through the tunnel and have access to internet through the internet connection on your computer.
For further details take a look to this document:
- http://www.cisco.com/c/en/us/support/docs/routers/3600-series-multiservice-platforms/91193-rtr-ipsec-internet-connect.html
Don't use Any on your ACL statements for split tunneling purposes.
Let me know how it works out!
Please don't forget to rate and mark as correct the helpful Post!
