qmail and procmail for forwarding messages

[Becks]

After installing qmail (which replaces sendmail with its own program) procmail stopped forwarding mails.

An entry in .procmailrc like:

:0 c
! mailadress@host.com


simply did nothing !

Reason and solution: qmail installs and replaces the original sendmail program by it's own version (located in /var/qmail/bin) and procmail doesn't find this one.
After creating symlinks from /var/qmail/bin/sendmail to /bin/sendmail and /usr/bin/sendmail everything is running fine now.
