I have one user on our RT 4.4.1 system whose emails to our email gateway always get bounced back.
I requested that she send the email headers for one of these messages… it reads:
Delivery has failed to these recipients or groups: firstname.lastname@example.org A problem occurred while delivering this message to this email address. Try sending this message again. If the problem continues, please contact your helpdesk. Diagnostic information for administrators: Generating server: googlemail.com email@example.com Remote Server returned '< #5.0.0 smtp; The account firstname.lastname@example.org is disabled.>'
I’m specifically wondering about the message
< #5.0.0 smtp; The account email@example.com is disabled.>.
The user’s account is active in RT and has a valid email address, and the user has no problems interacting through the web interface.
/var/log/*.log for occurrences of the user’s email address, and didn’t find any hits, so I know that there isn’t anything in
The other thing to note is that other users with emails in the same domain have no issues sending mail. I’m not sure how to continue trouble-shooting.
