Just to augment on Terry's reply, what Orin needs is an SMTP-aware antivirus program such as NAVIEG (Norton AntiVirus for Internet E-mail Gateways -- or whatever Symantec calls it this week), which is similar to IMail AntiVirus as the CarrierScan engine of the latter was developed by Symantec. However, you could save a lot of money by purchasing Declude Virus which is essentially a product that will turn an ordinary command-line virus scanner such as [dirt-cheap] F-Prot into an SMTP-aware program. Thus, an on-demand scanner which, without Declude Virus, could/will wipe out entire .MBX files among other "niceties" can be used safely. R. Scott Perry, the author of the Declude product line, also seems to understand MIME segments and all their diversities/complexities better than programmers at large AV companies. It is not uncommon that a virus be imbedded in an obscure form of MIME encoding which Declude Virus + command-line scanner will catch whilst certain costly SMTP-aware scanners will let through.
