The SA glue code is pretty tiny.  The anti-virus glue code in
mimedefang.pl is substantially larger, making up more than 50% of all
the lines in mimedefang.pl.  Since people are unlikely to be running
more than one virus scanner, it means about 50% of mimedefang.pl is
just dead weight.

More code isn't only more RAM; it's also more attack surface.  Security
best practices indicate not installing code you don't need.

As per my posting at
I don't think MIMEDefang is fixable with little tweaks.
