SMTP content filter engines, including (1) GFI MailSecurity for Exchange/SMTP prior to 7.2, (2) InterScan VirusWall prior to 3.52 build 1494, (3) the default configuration of MIMEDefang prior to 2.21, and possibly other products, do not detect fragmented emails as defined in RFC2046 ("Message Fragmentation and Reassembly") and supported in such products as Outlook Express, which allows remote malicious users to bypass content filtering, including virus checking, via fragmented emails of the message/partial content type.
