Chatted online with ATT, they say it is an outage issue, but no idea when it will be fixed. Big problem with a lot of users here in San Luis Obispo, CA.

Derek:

Is it just an outage issue, or is it also related to the Mail Server verification issue;

I've fixed it on one e-mail account but not my wife's (sigh ...)

Please let me know if you could when its "fixed" in your area. I'm in San Diego, North County.

Thanks

Yep, can't send email when the 'from' address isn't the sbcglobal.net one. I'm using my own domain, so this sucks. If that's their latest fight against spam, they went too far.

Indy:

I was able to trick the server; go to the web portal for your ATT/Yahoo Mail, find the Mail Accounts management page and "add" a new e-mail address and insert your domain's e-mail address. Click "verify" and Yahoo will send a test message to your domain which presumably you have set up to redirect the e-mail back to your Yahoo account. The test message will include a verification code that you need to finish the verification process on your newly "added" e-mail on the Yahoo portal.

Once I did this, my e-mails sent with my long standing Outlook Express POP account configuration worked fine.

Good luck.

BTW, Tech Support at ATT/Yahoo are absolutely clueless about what is going on and can not explain what was chnaged or what the Instructions I linked to in my first message (above) even mean. This has to be one of the worst tech screw ups of all time. No coordination, customer prep, roll out or proper support - at all.

You can use your own domain in the "From" address IF you enter it as an alternate email address in your Yahoo mail options AND you only use lower case letters.

For some unknown reason, Yahoo changed to forcing the email address to be all lower case on April 1. I spent over an hour with tech support and only after demanding to speak to a supervisor did I get through to level 2 and they said they were getting a tremendous number of calls. (This was at 3 AM PST.)

While on the phone with support, I remembered that about a year ago or so the signon was changed to only accept lower case. I tried changing my from address to all lower case, and I was again able to send using my own domain as my "From" address.

Interestingly, AT&T tech support claimed that they were totally unaware that Yahoo had made this change.

As an alternative, instead of using smtp.att.yahoo.com as your smtp server, switch to smtpauth.sbcglobal.net and turn off the security settings.

All of a sudden this morning (April 5, 2008) I'm getting a pop-up in Apple Mail (below) that I can't send trough smtp.att.yahoo.com no matter what return address I use or to whom I send. What do they mean by "verified"? The web site looks like it is for something else.

I'm able to send through my web host's smtp (for low volume only) but not ATT. Did I screw something up... or did ATT?

Help!

The server response was: From: address not verified; see »help.yahoo.com/l/us/yahoo/mail/o···-07.html

Use the pop-up menu below to try a different outgoing mail server. All messages will use this server until you quit Mail or change your network settings.

Please see the attached document above (the 553.PDF) that should explain and tell you how to fix the problem.

I only have ONE DSL account xxx@sbcglobal.net. For years and years I've been able to send using different "from addresses" like xyx@mydomain.com or abc@anotherOfMYDomains.com through the smtp.att.yahoo.com server using Outlook or Apple Mail. All of a sudden I can't!

I don't have sub-accounts. Not even sure what they are. Six years ago I signed up with DSL and they gave me one account.

I was able to use many different return addresses when sending mail. Now I can't?

I'm totally confused.

Well the thing is you still can do what you previously did. The only difference is now it has to be legit addresses and they have to be listed in the »mail.yahoo.com options pages.

In anotherwords the address has to exist, because Yahoo! is now going to verify it does. As well as DNS checking

Download the PDF in this thread above in my last post. Read that document to it's entirety. It will make more sense to you then.

Step 2 tells you how to authenticate an address so you can use that different one if you wish.

OK, I added a new "from" address to my prime account via the link above. It worked.

1. I was able to use any "from" address yesterday. Did this all change this morning? There was no mailing about it earlier?

2. Do you know if the cable companies (Comcast) have this new "from" mail verification rule?

Honestly. It is easier to just use my web host's smtp. If you have 20 different "from" email addresses (such as zzz@my_company.com and xxx@my_company.com) you now have to have ALL of them verified in advance in order to use the att smtp server. What a major PITA. Tell me how this is an improvement in service?

Um you do realize its a global call center? Just because its 3AM PST doesn't mean the whole world is asleep.

Also having just gone through setting up and verifying an alternative e-mail account it was quite easy and is well documented.

Don't bash AT&T for things they make quite easy and painless.
