I'm firmly of the opinion that there is always something else that may happen that I haven't thought of!  We don't know what the next exploit might be that gets exploited by virus writers.  If you want to protect against all viruses without using a virus scanner then you should block all attachements and probably strip all html content too.  Theres no telling for sure what attachements may have viruses in them.  One example, theres a known vulnerability in Windows XP which can be exploited by a carefully constructed mp3 or wma file.  Presumably that could be exploited by a virus writer, but who would have expected an mp3 file to contain a virus - its not even executable!
