I have a problem with Dovecot configuration.
I installed full pack VestaCP (Hosting Control Panel), it's included Dovecot.
(Early, i configure many servers with this panel, and everything works ok)
After adding new email address by panel, i trying connecting by Apple Mail and Mozila thunderbird, but mail client shows error about invalid email/password.
In /var/log/dovecot.log
i finded this:
imap-login: Info: Aborted login (auth failed, 2 attempts in 1 secs): user=<>, method=LOGIN, rip=x.x.x.x, lip=y.y.y.y, TLS, session=<zzz>
Why "user=<>
" ? I think there should be an email there, but it's empty?
In the mail client the login is specified, of course.
If it's help:
- OS Ubuntu 16.04. AWS EC2.
- Ports 143, 587 in AWS Security Groups opened.
