I'm attempting to set up postfix + dovecot + postfixadmin on Ubuntu 20.04 using the provided packages.
This is what the SASL configs in main.cf look like: root@mailserver:/etc/postfix# grep -i sasl main.cf smtpd_sasl_auth_enable = yes smtpd_sasl_type = dovecot #smtpd_sasl_path = /var/run/dovecot/auth-client #smtpd_sasl_path = /var/spool/postfix/private/auth smtpd_sasl_path = private/auth smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination smtpd_sasl_security_options = noanonymous smtpd_sasl_tls_security_options = $smtpd_sasl_security_options smtpd_sasl_local_domain = $mydomain Every minute I get: Sep 25 22:36:28 mailserver postfix/smtpd[6385]: warning: unsupported SASL server implementation: dovecot 39,1 70% Sep 25 22:36:28 mailserver postfix/smtpd[6385]: fatal: SASL per-process initialization failed Sep 25 22:36:29 mailserver postfix/master[6191]: warning: process /usr/lib/postfix/sbin/smtpd pid 6385 exit status 1 Sep 25 22:36:29 mailserver postfix/master[6191]: warning: /usr/lib/postfix/sbin/smtpd: bad command startup -- throttling in the /var/log/mail.log root@mailserver:~# postconf -a cyrus dovecot root@mailserver:~# What am I missing? Thanks.
