Hello there. I was fed up with some repeated spam that was coming our way, and had the idea that it would be great if the clamd could stop these. (We use plesk with postfix+clamav)

So, I did something like this:

$ echo This is a text line from the annoying spam | sigtool --hex-dump >> /var/lib/clamav/customsig.ndb

I also added this to the beginning of that line: Spam.kalfaoglu.net.1:0:*:

However, trying this out,

$ clamscan  badmail.txt
badmail.txt: OK
----------- SCAN SUMMARY -----------

... does not yield to a detection.. what am I doing wrong?

Many thanks, -t
