Qmail notes

This is for a Qmailrocks install. This may not work on other qmail installations. Or it may work. Or it may screw up up your mail queue; or your qmail installation; or your whole machine; or your friend's machines. That is the beauty of qmail.

qmail.sh

This is the missing mail control script. It's crude, but it works. Note that this won't fix queue problems. Look for the qfixq script.

Note the "spamon" and "spamoff" commands. These are useful for turning just spam/virus filtering off. Sometimes spamassassin or clamav get messed up and it is preferable to get mail back online without spam/virus filtering while you try to figure out the problem.

Shell command aliases

Add this to your bash aliases.

alias lsq='find /var/qmail/queue -type f -exec ls -l {} \;'

User Aliases

Why isn't this documented properly? Maybe this is still an experimental command. At any rate, I had to try both way just to figure out which comes first in the argument list. This creates a new addres, alias_user@example.com. All mail sent to alias_user@example.com will get put in the mailbox for real_user@example.com.

/home/vpopmail/bin/valias -i real_user@example.com alias_user@example.com

alert: cannot start: unable to open mutex

Looking at the log file, /var/log/qmail/qmail-send/current, shows lots of "alert: cannot start: unable to open mutex" error messages. I don't know how this happened. I had shutdown qmail. Maybe I had done a hard reboot of the machine. I don't remember. Oh, good grief! Why don't I stop complaining and ditch qmail? No amount of "perfection" is worth the hassle of this thing. Only autistic savants could love qmail. At any rate, this fixed the problem (Yeah, this is obvious, right?):

qmailctl stop
touch /var/qmail/queue/lock/sendmutex
chown qmails:qmail /var/qmail/queue/lock/sendmutex
qmailctl start
