I have dovecot running on virtualmin.
- I can send mail from the server, via the Usermin webmail interface
- I can also send mail to the server, and see it in webmai.
However, I have been unsuccessful in connecting on mail client to either IMAP or POP3.
The only changes to default dovecot configuration are these:
-
10-auth.conf.
disable_plaintext_auth = no
-
10-ssl.conf
local_name mail.redacted.com {
ssl_cert = </etc/letsencrypt/live/redacted.com/fullchain.pem
ssl_key = </etc/letsencrypt/live/redacted.com/privkey.pem
}
What the maillog show when trying to connect an email client is:
imap-login: Disconnected (auth failed, 1 attempts in 5 secs): user=<admin@redacted.com>, method=PLAIN
pop3-login: Aborted login (auth failed, 1 attempts in 12 secs): user=<admin@redacted.com>, method=PLAIN
