The explanation is probably in you maillog file.  Sendmail (or whichever 
MTA you use) should log every connection it receives and log things like 
envelope sender, time of day and message ID.  Then grepping that message 
ID should tell you what happened to your mail.

Also you should put MS in verbose mode or run it in debug mode to get 
the full details about what is happening.

Verbose mode (MailScanner.conf):
Log Spam = yes
Log Silent Viruses = yes
Log Dangerous HTML Tags = yes
