I have followed the tutos about mail server.
I’m on the part of roundcube and have problems:
the postfixadmin works and i created a user.
errors when testing config roundcube:
Trying to send email…
SMTP send: NOT OK(Authentication failure: STARTTLS failed (Code: ))
and testing connection roundcube
Connecting to ssl://w3bmail.marmogres.tech…
IMAP connect: NOT OK(Login failed for [email protected] against w3bmail.marmogres.tech from [my IPv6] Could not connect to ssl://w3bmail.marmogres.tech:993: Unknown reason)
The let’s encrypt certs are configure in the /etc/nginx/site-enable/w3bmail.marmogres.tech
- Ports are open in UFW
- i have the A and AAAA DNS entry OK for w3bmail
have you an idea about the problem?
