[Mimedefang] SoBig.E slipping through

[Minica, Nelson (EDS)]

Not using anything for virus scanning at the MTA.  If this one virus can
slip attachments past mimedefang then others can too.  Perhaps I shouldn't
trust $fname to actually contain the filename...?

What are you using for virus scanning?

MIMEDefang, by design, lets through zip file (and unknown extentions such as
.zi)

Unless you wish to allow text/plain only, you can't expect MIMEDefang to
protect you from all Email worms.  Clamav (among others) does a nice job of
catching things in zip files.
