I'm trying to set up a very simple anti-spam filter that automatically
replies to any mail message, asking the send to put 'foo' in the header.
Any mail messages without foo will not be read. Later I will expand this
to automatically put the foo there, but for now I'm stuck at a more
fundamental level.
I wish to do this on the computer at university, where I do not have
root access. Procmail is not installed. I:
1) Installed procmail and formail in $HOME/bin
2) Put a .forward which has: "| exec /home/duke/davek/bin/procmail"
3) Wrote a few lines in a file antispam.txt which has a short
explanation.
4) Wrote a .procmailrc which is almost a carbon copy of that in the
procmailex(5) man page.
Any ideas what is wrong ? The .procmailrc and logs are below.
------
PATH=$HOME/bin:/usr/bin:/usr/ucb:/bin:/usr/local/bin:.
MAILDIR=$HOME/Mail # You'd better make sure it exists
DEFAULT=$MAILDIR/mbox
LOGFILE=$MAILDIR/log
LOCKFILE=$HOME/.lockmail
VERBOSE=yes
SENDMAIL=/usr/lib/sendmail
FORMAIL=$HOME/bin/formail
:0

-A"X-Loop: davek(_at_)medphys(_dot_)ucl(_dot_)ac(_dot_)uk" ; \
cat $HOME/antispam.txt) | $SENDMAIL -t
:0
$MAILDIR/spam
where antispam.txt shows a message about inserting foo in the header.
