All emails I sent yesterday from my pacbell.net address were returned to me as undeliverable. Even gmail and aol addresses. We were told by mail and here online our emails would not be affected. What is happening. My address is -------

Thank you, ----

...my pacbell.net address were returned to me as undeliverabl

So presumably that error report was part of a bounce message. There's usually some kind of reason or maybe a cryptic reason error code as to why the message bounced.   What does that message say exactly?

Hmm, I don't know.  Perhaps doing a search for that error message may turn up some solutions.  This could be a SMTP server problem or a problem related to using the grandfathered pacbell.net account.  You may have to get @ATTU-verseCare to help.

I can't.  I also use TB and haven't seen any interruption in service.  But then I have an att.net email domain.  Do you?  Or is it one of the grandfathered domains like pacbell.net, sbcglobal.net, etc.?  There's been a number of reports with problems with them lately in these forums.

For TB all I can suggest is to delete your passwords (or at least the one for inbound.att.net) by going into the TB preferences/options, clicking Security and its Passwords tab.  Then click Saved passwords and delete the inbound.att.net password.  The first time you try to access the POP server when getting new messages TB should prompt for the password.  Enter it (TB's password list will be updated) and hope for the best.

Note, as a control experiment you should see if you can log into the webmail through your browser using that password.

Not solved.... After the Verizon merger, my account signs me out every hour. I've changed my password and nothing has changed. I've attempted contact with Verizon, but they state that they aren't doing the email thing any longer. Can't even break into an appropriate contact through Yahoo. What more can I do? This is a real inconvenience, as it will sign me out while I'm in the middle of a message.
