Can't send emails : SMTP Error (454): Authentication failed

[calport]

There is this message in the Virtualmin forum:

warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory

Well, digged the web and nearly drove crazy. By entering ls -la /var/spool/postfix/var/run/saslauthd it had shown, that the directory is empty. After literally hours of search i came across this. Stop the instance of saslauthd and restart it. /etc/init.d/saslauthd stop-instance saslauthd /etc/init.d/saslauthd start-instance saslauthd this fixed it. Just in case. Best
