Hi
I picked up the small skript "checkattach" from Noel G. Mistula and
modified to do "Subject:" type filtering.
Do the following:
1. Install the script in /usr/local/bin.
2. chmod +x checksubj
3. Add this skript into your user's .qmail files and - if applicable - into
/var/qmail/alias/.qmail-default (first line:)
|/usr/local/bin/checksubj
~/Maildir/
etc.
4. Modify the subject text fields in "checksubj" to your needs, eg. add
"|*insurance*". The script evaluates the string case sensitive! It allows
wildcards, but be carefull!
5. The sender becomes the E-Mail bounced.
6. You can watch the results (and test the script) viewing your Maillog.
cheers.
eh.
