Can't send emails. Receive them OK

Started Friday on all devices, including my phone.

 

On Mozilla Thunderbird I get the following message:

"An error occurred while sending mail. The mail server responded:  5.7.1 We were unable to deliver your message. Please try resending your message by adding some text.. Please check the message and try again."

 

On Yahoo web I get:

"Unable to send message

Help!

I do business on this account and it's critical to me.

Re: Can't send emails. Receive them OK

Do you have a legacy email account (sbcglobal.net, etc.)?  If so try changing your password (Forgot ID/Password).  Once you do that, or even if you don't have a legacy account, change the password in your Thunderbird to a secure mail key.  Read this for details.

 

To change you Thunderbird passwords access your Thunderbird preferences, security, passwords, saved logins.  Delete the password entries for POP or IMAP and SMTP servers.  The next time you send and and the next time you receiver you will get dialogs prompting you for the new password.  Enter it and be sure to click the checkbox in the dialog to remember the password in the password manager (i.e., the save logins).  For example, send a email to yourself to get those dialogs.

Re: Can't send emails. Receive them OK

Thanks, that worked! I was imagining someone had hacked my account and sending spam, so happy a PW fixed it.

 

Thanks again.

Re: Can't send emails. Receive them OK

Which worked exactly? 

 

  1. You had a legacy account so you only changed the account password?
  2. You only switched to using a secure mail key?
  3. You changed both the account password and switched to using the secure mail key?

My theory about legacy account email problems being "cured" with a password change to force update the user accounting data is at this point, just that, only a theory.  I'm still looking for confirmation on this (I don't have a legacy account).  I keep recommending it but no one ever comes back to say this solves their problem.  That's why I am asking.

 

Using the secure mail key in place of the password in email clients is of course not a theory and just a good idea to do.  But I don't know if it is sufficient to just cure these problems.  Again no feedback.Man Frustrated

Re: Can't send emails. Receive them OK

I don't know what a "legacy account"  or a "secure mail key" are. I changed the password through AT&T,  then on my Yahoo page and then Mozilla. All seems to work now.

Legacy account: If you have an e-mail address that ends in something other than "att.net" (e.g. bellsouth.net, sbcglobal.net, prodigy.net, etc.)

Secure Mail Key: A string of characters generated from the AT&T web site that can be used in place of the password when utilizing an e-mail client that doesn't support oAuth.
