Unhappy No SASL authentication mechanisms using Ubuntu 20.04 + ISPConfig 3 + Dovecot


I followed step by step the guide "The Perfect Server - Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3)" to setup a new server. I works fine but I have problems with email.

The Monitor says:

Web-Server: Online
FTP-Server: Online
SMTP-Server: Online
POP3-Server: Offline
IMAP-Server: Offline
DNS-Server: Online
mySQL-Server: Online

The Mail log says a lot of times:

Feb 15 08:20:11 ubuntu postfix/smtpd[4576]: fatal: no SASL authentication mechanisms

Searched for other posts in the forum and I have no solution yet. Anyone can help me?
