Unable to configure mail server authorization?

Question

Email

I'm trying to set up mail according to the manual uraganltd.blogspot.com.tr/2017/10/postfix-dovecot -... ran into an
insurmountable problem smtp tries to connect for a long time, then resets mail logs with a timeout error

postfix/smtps/smtpd[9534]: fatal: connect #11 to subsystem private/proxymap: Connection refused
postfix/smtpd[9536]: fatal: connect #11 to subsystem private/proxymap: Connection refused

dovecot status
swears at the file, although it is in place and readable

service dovecot status
systemd[1]: dovecot.service: PID file /var/run/dovecot/master.pid not readable (yet?) after start: No such file or directory

dovecot logs when trying to test
here is a snag in this, it seems, but I can't figure out what's the catch

Answer 1

Look at the auth_mechanisms setting in 10-auth.conf
