This morning I discovered that I could no longer send e-mail through any of my 3rd party e-mail accounts.

After speaking to level 2 support, I learned that Yahoo made a policy change to their SMTP servers as part of their ongoing effort to reduce spam.

There are two solutions:

1. Call u-verse support and ask to speak with level 2 to have port 25 unblocked. This will allow you to connect directly to your 3rd party SMTP server for sending e-mail. Once this is done, contact your 3rd party support for the correct SMTP settings to use.

or

2. Register your 3rd party e-mail accounts for use with the AT&T SMTP server. Each account must now be verified before outbound e-mail will work for non-att accounts. Instructions for this process can be found here:

http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html

Once you have verified all of your accounts, it will take some time for the changes to propagate through all of the yahoo mail servers, but I was able to send mail again after about 15 minutes or so.

Your third party email providers should be using SSL encryption. That changes the port away from 25.  I know for gmail the SSL-SMTP port is 465.

My third party provider just so happens to have a secondary SMTP port. Once I found out Yahoo was blocking port 25 I call my third party provider and they told me what secondary port number to use instead of 25. They also told me most SMTP software supports a secondary port so this should/could work with other third party providers.

I think I got bitten by this. But my emails did not start getting bounced back to me until today 4/8/08. No wonder I got no response from people I sent email to!

Also seems they added some new servers! Add plus in front of your pop and smpt server addresses. http://help.yahoo.com/l/us/yahoo/mail/yahoomail/mailplus/pop/pop-36.html

Why not just use the AT&T-designated servers?

That is a ATT designated server! 
pop.att.yahoo.com    & smtp.att.yahoo.com
or you can now use
plus.pop.att.yahoo.com & plus.smtp.att.yahoo.com


I was wrong the plus servers may only be for pop.yahoo.com and smpt.yahoo.com.

So after completing the instructions I still can not send email? I did it last night and this morning I still get 553 errors!

For right now I am going to bypass the AT&T servers to send mail. But that is not a permanent fix as my mail server is running off a dynamic IP and will get blocked by a lot of ISP’s.

Actually, I just got off the phone with Level 2 tech support, and they claimed that address verification doesn't work any more due to Mordak the Preventor-type security procedures they have installed.

However, I just followed the instructions on the link, and address verification appears to be working now. It remains to be seen if this is a hiccup, or if address verification really works with the new procedure.

Give it a whirl, however, it can't hurt.

Hope this helps.

Well I believe AT&T techs like I believe used car salesmen! Not at all! The address verification did work for me but it seems to be case sensitive! Tim@mydomain.com dos not work when tim@mydomain.com does? Can someone verify?

Wish they would offer static IP’s so I could bypass AT&T servers and have my mail delivered.
