Qmail Commands

Though I am not a qmail expert. I would like to share some commands that I know for qmail MTA.

To check mail queue:
/var/qmail/bin/qmail-qstat



To flush mail queue:
qmailctl doqueue



To check SMTP log(running):
tail -f /var/log/qmail/qmail-smtpd/current

@40000000587db4390923aefc tcpserver: pid 14016 from 122.144.8.44
@40000000587db4390937db0c tcpserver: ok 14016 smtp.abc.com:122.144.8.83:25 mail.xyz.com:12.44.08.44::29044
@40000000587db4391081076c tcpserver: end 14016 status 0

14016 is the process ID for a mail.



To check mail delivery log (running):
tail -f /var/log/qmail/qmail-send/current

8216 is the process ID for delivery.



To set smtproute (relayhost):
