Here's a quick guide on how to SAFELY modify a user's .qmail files on
an SMEServer.
You should be familiar with the following man pages (at least)
man -M /var/qmail/man dot-qmail
man -M /var/qmail/man qmail-command
man -M /var/qmail/man preline
Let's assume the user name is bob. You can change instances of "bob"
below to suit your needs.
- create a new .qmail-filter file for bob that contains the programs you
want and possibly default delivery instructions if you want mail
to be delivered to bob's Maildir/ if the script fails.
cat > ~bob/.qmail-filter << EOF
| /path/to/your/script with optional arguments
./Maildir/
EOF
- ensure the ownerships and permissions are correct
chown bob.bob ~bob/.qmail-filter
chmod 644 ~bob/.qmail-filter
- use the SMEServer manager to forward bob's mail to
bob-filter
This approach will ensure that your changes will survive any future
modifications to bob's account (such as adding him to a new group for
example). If you don't use this approach, bob's .qmail file will be
overwritten with the default delivery details, which is not what you
want.
If your command requires the existence of a UUCP style "From " header
(not to be confused with an RFC822 style "From: " header) then you may
want to prepend the command with preline
| preline /path/to/your/script with optional arguments
Be aware that preline demands that the program it calls accept the
ENTIRE message, so if your script closes STDIN before reading it all,
preline will complain and you'll see the following messages in
/var/log/qmail/*
deferral: preline:_fatal:_unable_to_copy_input:_broken_pipe/
