Seamless e-mail virus scanner?

[Bill Parker]

Hi All,

        Is there a seamless drop-in email virus scanner program which
will work with qmail v1.03, tcpserver, vpopmail, and qmailadmin packages
installed on my system, one system in here got munched by the love bug
virus.  Any ideas, my mail system works nicely, but don't want to have
to install a lot of patches to get something like this working.
