AT&T Mail Setup

For last the few weeks my ATT email in Mac mail no longer works consistently when using my 2012 iMac with Catalina iOs. I have created the encrypted password key which will work for a few days until I can no longer send a simple email with Mac mail.  It will function for a few days if I delete

Is there a way to restore my contact list? Thank you.

Why does my email address say "Noreply" before my sender address?

This morning, I suddenly found my emails organized by date. I don't want this -- it wastes space on the screen. How so I get back to where I was yesterday?

Hi I'm Using ESP for emailing our Subscribers. But now our ip is delivering in Spam Folder.Kindly help me overcome this issue.

My email has an @sbcglobal.net address and I access thru Yahoo Mail. I have looked at previous postings for help, but they were old and led nowhere with today’s ATT and Yahoo mail sites.  When I leave ATT, is there a way to continue to access this email address?

I have a subaccount that is now linked to my main email account and email from both are coming into my main account. How can I unlink them to be 2 separate email accounts?

Created a new email - [email scrubbed]. Want to setup email forwarding from account [email scrubbed] to my yahoo email. I have has ZERO success. I click the verify link in new email and it's not working!

Just signed up for Yahoo Mail Plus and keep getting AT&T Error Code while trying to verify the email address to which my AT&T emails are to be forwarded. Have spoken with 4 different AT&T support members and none of them could figure out what to do. The last representative instructed me

I have an older swbell.net account and under it, I have subaccounts. For whatever reason now I can not get into them and can not reset them since it appears some how they are now assigned with "This subaccount is linked to a user ID. You don't have permission to edit the password." Which is crazy. b
