Hi Marc,
this is the output of netstat -tanp (I only removed the line showing the
details of my ssh connection):
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
PID/Program name
tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN

tcp6 0 0 :::80 :::* LISTEN
26990/apache2
tcp6 0 0 ::1:10023 :::* LISTEN
28575/postgrey --in
and indeed it there is no tracce of dovecot there, but what should I do
then? "service dovecot status" says the service IS active...
Thanks!
