Can't Send Mail To Outside Addresses In Mail Applications

I am currently running mac os x server 10.4 and using the mail server. I started out using WebMail. It worked fine, I could send and receive to and from anyone. Now hat i have multiple addresses it is easier to use a client like mail.app or mozilla thunderbird. I can send and receive mail to and from addresses hosted by my server fine. I can only receive mail from outside addresses i cannot send mail to them. Does anyone know what I can do to fix this?

Without knowing more about your configuration it's hard to say.
Most likely your client computer is not in the allowed networks (while webmail running of your server was). But that is a guess.
If you need more info, please post the unmodifed output of postconf -n and some log snippets.

Can't send mail to outside company

I wrote a javamail program, I can only send mail to internal email address, but not to outside, any reason that could be?
Thanks for your help.
Dan.

I'm replying specifically for GroupWise but MS Outlook/Exchange will in essence be the same.
When you send an email from your PC using GroupWise, the GWIA (ie the SMTP server) is what actually sends the email. This is on a server somewhere but NOT on your PC.
When using Javamail, you are really operating another smtp client. The GroupWise GWIA is likely configured not to accept relaying. If it is, for example if you use a mail filtering system so relay all mail, it is likely configured to accept relaying from only that IP address. Your PC (or wherever you are running the Javamail from) is unlikely to be an 'allowed' relay source.
In GroupWise you can add as many relay sources as you like under the GWIA object. Again, Is imaging Exchange is similar.

Postfix/smtp[8437] Operation timed out can't send mail to 1 address

server 10.4.5 running mail, filesharing and website.
The mail server has been up for months working fawlessly. We have one address (domain) where we can't send mail, and users at that address can't send us mail.
All other mail functions on both ends seem to be functioning fine.
They seem to be running exchange as a mail server, but i don't have other details from their side. DNS/MX records all look like you would expect.
This has me stumped.
i turned debug level loging on and got the following smtp message written to the log when i tried to mail to an address at that domain.
Feb 23 20:45:10 fileserver postfix/smtp[8437]: 775401AFD61: to=<[email protected]>, relay=none, delay=31, status=deferred (connect to anhc-mail.anhc.org[24.237.2.213]: Operation timed out)

Yes, good luck to them.
relay=none
doesn't look so good.
Of course, a successful outgoing message should look something more like:
Apr 8 11:41:05 server postfix/smtp[2300]: F1D4D3B8A27: to=<[email protected]>, relay=mail.someobfuscatedserver.com[6x.20x.148.1x6], delay=5, status=sent (250 2.0.0 k38FYfDS023848 Message accepted for delivery)
I take it you can send to any/all other mail addresses (servers) ?
Here's a thought:
Some time ago, I had to edit the helo_checks config of postfix, for a windows mailserver because their AntiVirus was horribly mangling their outgoing mail, helo-ing as <fix-your-dns>.local
Point being that .local anything is not a viable tld for anything in the public realm, and certainly won't work with the rest of the world in terms of DNS.
That might be the work of Norton's break-it-for-you addon for Windows Exchange mailservers, not sure.
Please post the output of:
postconf -n
on your server,
and the mail.log file content when they try to send you an email (confirm via telephone and watch for it).

I have done a lot of reading and playing with different settings, just can't get it to work. So I decided to ask for some help here.

It sounds like you have more than one issue.
First.. let's just look at sending mail to outside addresses....
You have relayhost setup with an improper setting. relayhost should either be blank, if you want your server to make delivery- or it should contain the host name of your ISPs smtp server (something like smtp.isp.com). You currently have an email address in this field, that won't work.
The next issue is not real clear to me. You may need to clarify.
You say that the recipient sees "[email protected]" as the return address? The return address is set in the mail client. If you are using a mail program (Mail.app, Entourage, etc), then make sure your email address is set properly. If you are sending from WebMail, then let me know and I'll send directions to fix it.
Please provide additional information.
Specifically, try to isolate what appears to be two separate issues
1. Can not send mail to outside addresses
2. Mail sent to internal addresses is successful, but shows wrong return address
Is that correct?

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..... 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?

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.

Can't send Mail on dial up Earthlink?

We have set up a sub account for a grandson on Apple's Mail application. After many problems finally got Mail to receive message but can't send mail.
He gets the message: "his email earthlink.net can not be contaced on port 25, message delivery failed." The primary account works well.
He is on an eMac 10.3 with dial up to earthlink.net

Although I have cable modem service at home with Time Warner (RoadRunner), I've kept an old Earthlink dial-up account for use when traveling in case a high speed wired or wireless connection isn't available which is becoming less common.
If Earthlink is your ISP used for connecting to the internet via dial-up access, I use the following Earthlink SMTP settings for my Earthlink account.
Outgoing Mail Server: smtpauth.earthlink.net
Server Port: 25 (which should work if connecting to the internet via Earthlink dial-up access).
Use Secure Sockets Layer (SSL): Off or not selected.
Authentication: MD5 Challenge-Response
User Name: The entire Earthlink email address.
Password: The account's password - the same password used to check the incoming mail server for new messages.

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.

After Leopard upgrade can't send mail in Apple Mail with dot mac account.

Just upgraded to Leopard and now I can't send mail through Apple Mail. Checked smtp and that's OK. How do I check what ports are open? That may be the problem. I looked at the Apple trouble shooting page and did everything there except the port check.
Any other suggestions?
Thanks,
Lou

Fixed my own problem. I put in the SMTP address but didn't save. Once I saved it worked.

Can't send mail - server properly configured and up

I'm unable to send mail. Here's roughly the sequence of events that
got me where I am:
1) Connect through a firewall using VPN (the Cisco VPN client)
over the wireless interface
2) Compose a message, and click 'Send'
3) The server is down, so I get the "Can't send e-mail" pop-up
dialog
4) Click 'Try later'
5) Reconnect later while the server is up, and try to send
6) Still see the "Can't send" pop-up
Steps 3) and 4) happened a lot. In particular, turning on the
wireless interface in order to connect over VPN causes Mail to try
(and fail) to connect to the server.
The server is up; I can reach it with "telnet <server> 25".
Moreover, Mail's own "Connection Doctor" says it's able to connect
to the server.
This configuration worked until the sequence of events described above,
and nothing on the server side has changed since.
I've tried everything I can think of to get Mail back in a working state.
Notably I've deleted the contents of "Outbox", quit Mail, and then restarted.
I've also deleted and re-created the server configuration, without success.

Two additional data points:
1) I found a mail server I could use from outside the firewall.
When I added that server, and closed the VPN session, Mail was
(finally!) able to send. (But see below why you shouldn't rush
to blame VPN).
2) When there are two mail servers configured in preferences, the
"Can't send mail" pop-up gives you the list of choices. If you
select an alternate server from the list, the "Try selected
server" button ought to try the new server. Instead, the
pop-up reappears, still complaining about the old server.
As for why I'm not prepared to blame (only) the VPN:
* Note that the server is perfectly accessible; telnet works,
and Mail's Connection Doctor says the server is up.
* Point 2) above indicates some problem in Mail with the logic
for retrying access to the failed server.

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

Suddenly can't send mail

I have often received the alert box that the selected server can not send the mail and I have to change the server,or wait, or restart mail to get it to work. This is annoying, but I have dealt with it (although I'd like to know what's going on). But, now, it seems I can't send mail at all, from any server, with a restart or otherwise. It's been happening for the last day.
Can anyone lend a hand? Is it a problem with Apple? I've chosen a variety of different servers (I have many e-mail accounts set up). I've relaunched. Tried to send from various e-mail addresses (although my .mac is my default). No luck.
Thanks for the help,
J.

We have the same problem here and for a few weeks we've resorted to signing in to a browser email program as mac mail's password isn't recognized by the server.
