Receive mail - auth fails

Help! (Home for newbies)
1
Operating system AlmaLinux 8.9
Webmin version 2.105
Virtualmin version 7.9.0

Thunderbird is not able to authenticate when trying to receive mail - keeps asking for the password

/var/log/maillog says…

imap-login: Disconnected: Connection closed (auth failed, 3 attempts in 14 secs)

  • user/password is correct
  • let’s encrypt cert for mail subdomain was issued (so it’s not an OSCP issue, besides i tried disabling the check)
  • connection is set to SSL/TLS, normal password

When you create new account did you use automatic config as that worked fine for me.
You didn’t mention the port, is it set to 993

Normally means your using wrong username or password.
fail2ban may block :slight_smile:

port is 993 and fail2ban isn’t installed

i’m using the same credentials as i do to log on to v-min which should be the same as used for email

Did you remove fail2ban and its part of virtualmin install.
When the server says auth failure then its the username or password, maybe its the username format.

5

fail2ban wasn’t installed, perhaps because i chose the minimal install for v-min - the module is there and i can install it if i want but i usually use CSF though that’s not installed either at the moment

the user name format is <usr>@domain.tld - that always worked before, but i also tried <usr>.domain.tld

6

(auth failed, 3 attempts in 20 secs): user=<user@domain.com>

Is the user=<user@domain.com> matching the user in edit user in virtualmin
