Can't send mail rcphosts blocked

Hi folks for some reason I'm unable to send email at home. Works everywhere else except at home. I'm using a POP account and when I try to send a mail I get the following error message.
The server response was: sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
I know the address are good because I'm replying to recieved emails which I can still get, and I know the settings are good because I use the same account from my work machine. Pinged STMP server and thats ok and I've firewall turned off
Any suggestions?

Andrew,
Goggle with rcpthosts, and you will note several topics about this problem. One of them is pasted below:
http://forum.qmailrocks.org/archive/index.php/t-352.html
It is a form SPAM protection to such a list, but I don't have such a service.
One thing mentioned is the need to Authenticate the SMTP -- how are you authenticating this SMTP (btw, you keep misspelling SMTP in your posts)?

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

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!

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.

BLS Send Mail Action Block Requires SMTP Mail Server Mail Account

My SMTP Mail Server does NOT require authentication. It appears as if MII Ver 12 requires a mail account to be filled in on the BLS Send Mail Action Block. If the mail account field is left empty the transaction fails (error - mail account cannot be blank). Transaction works without the mail account on Ver 11.5 but Ver 12 requires the field to filled in. Please advise whether this is a new requirement in Ver 12 or a bug that needs to be addressed.

Hi Sam,
What I think is, it requires one mail account to send the mail and one to receive it.
There is no restriction on receiver that can be anyone. But the sender needs to be known that some mail has been sent from his mail account. So may be because of this the added authentification is required. It will use that mail account to send the mails.

Can´t send mail on any account

Hi,
Suddenly all of my accounts can´t send mail...
it pops up a window saying mail can´t use this smtp, and it doesn´t matter what I choose for selected server, nothing works.
And if I change the outgoing mail server settings in preferences it does not change in the pop up.
I did not change anything.
I have tried to start new account but nothing works.

Gunz,
For your .mac account, if you are using the smtp.mac.com as the Outgoing Server, change the Port to be Port 587, and test. Although you are using many different venues, more and more ISPs are blocking Port 25 for all but their own SMTP. Are the other accounts unrelated to your ISP? If so, their SMTP may need to be presented either on Port 587, or still another.
If you are having a problem with the SMTP provided by your ISP, then a change in policy may have been accompanied by a new name for their SMTP, or a new Authentication protocol.
More info, please, but first test with Port 587 and the smtp.mac.com.

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.

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.

Is there a fix for "can't send mail?"

I just spent 4+ hours on this forum and worked through all suggestions I could find - still can't send mail. It happened yesterday afternoon, from one moment to the next - suddenly all my three POP accounts are offline and there was nothing I could do about it. I checked with Entourage, same thing there as well, can't send mail.
I have no idea if this is connected with the problem in many posts about the "can't send mail" issue or not, but at least on the surface it looks like it is.
Any help is appreciated! Thank you.

Yes, there are complaint sites online where I've read hundreds of complaints that trickle in one by one on different dates.
Take a look at this post, and the comments below it:
http://www.lockergnome.com/usrbingeek/2007/04/12/comcast-blocking-port-25/
This is going to be an ongoing problem for different users, one at a time.
DSL users in my area are going through a similar issue with their CenturyTel email accounts. Over the last two years they have added a new smtp server and some people were transferred immediately to it, and others got added month by month (some were on smtp.centurytel.net while others are on smtpauth.centurytel.net). Then a couple of months ago, they started requiring login and password to the smtp server, but not for all users. I get a few calls a month for the next batch. Centurytel has gone with a 3rd party email hosting company so that they don't have to deal with it.
I'm trying to set up all clients with the latest changes, but they don't always work in advance of the changes. It's hit and miss. CenturyTel has said that they have posted notices on their help site, but who goes there?
Maybe they are just trying to manage their tech support load during changes?

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.
PowerBook G4 and PowerPC dual G5 (10.4.6 both) Mac OS X (10.4.6)

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

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?
