Filtering PDF-/XLS-/Image-Spam With ClamAV (And ISPConfig) On Debian/Ubuntu
There is currently a lot of spam where the spam “information” is
attached as .pdf or .xls files, sometime also hidden inside a .zip
file. While these spam mails are not easy to catch with e.g.
SpamAssassin or a Bayes filter, the ClamAV virus scanner can catch them
easily when it is fed with the correct signatures as ClamAV is built to
scan mail attachments.
