Having trouble to use preline command with Qmail's mail filtering.
When i use next syntax in .qmail-default file:
| /var/qmail/bin/preline /usr/bin/maildrop /etc/mail/mailfilter
... I get following error:
preline: usage: preline cmd [ arg ... ]
Just to mention that upper line is content of the file
Can you tell me what I'm doing wrong with this, and how to use preline command in this case?
Thank you in advance!
