Since upgrading to 10.8 (10.8.2), two separate users and two separate email accounts on our iMac are unable to send emails out using Mail; but we are able to receive emails. It has only begun since upgrading to Mountain Lion.
I see many posts about this similar issue, with many different possible causes and ways to resolve which none seem to work.
Anyone have any updates or ideas on how to resolve this issue? Everything worked fine until the upgrade.
Below is the error message we receive:
Cannot send message using the server smtp.att.yahoo.com
The SMTP connection to server “smtp.att.yahoo.com” failed.
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.
Trying to log in to this smtp account failed. Verify that the username and password are correct.
Thanks for anyone's help!
Really this has nothing to do with the OS, even if upgrading the OS broke it. It is a Mail settings problem or the Mail program itself.
Create a New account in the mail program with all the correct setting. You may have to delete the original account to be able to do this using the same Username and password. So make sure you Back Up all the mail that you now have.
If that doesn't work then switch to a REAL Email program as the one that comes with OS X is the worst.
Well that update may of updated the Mail program which, even though it is included with the OS, is not really a part of the OS. It is a separate program.
If you read these forum you will find many many posts about how poor an Email program Apple/Mac Mail is. Some have no problems, many have numerous problems.
There is nothing wrong with Mail, Apple's email program, despite what others might say.
All e-mail clients are sensitive to having the correct setup information entered into their configuration setup. They have pretty much the same inputs.
Verify that your username is entered correctly. In most cases it's everything to the left of the @, sometimes it's the whole e-mail address. Also, always make sure that after you make changes to the configuration settings that you not only save the results, but that you also Quit, not just close the open window, the e-mail application and restart it.
Often e-mail clients offer automatic configuration assistants that depend on typical conventions. That's why you may have to adjust some of the settings.
Example: When I worked for the Federal Govt., we used Microsoft Outlook, it configured the user name iaw convention and entered everything to the left of the @. This didn't work though because our IT department mandated the use of our 7 digit login ID used eleswhere within the Government.
No they're POP (AT&T) accounts. Not a big fan of AT&T but my wife doesn't want hers changed to something else so for the time being trying to resolve this SMTP issue in Mail.
About the only thing you can do is Delete these Account then Recreate them. I also use the ATT Yahoo Mail system for 3 of my email addresses and just did a test from one of them to my Gmail account and had no problem sending through the SMTP.ATT.YAHOO.COM servers. But then I am using Thunderbird as an Email client.
