keep in mind that some of the newer viruses (klez,ect) will basically generate 
this effect, even if neither your server or any of your users have been 

klez has its own SMTP engine, so it can send mail on its own.  it also, select 
a random "mail from:<address>" from the list of all users stored in the 
infected users contact list.  this behavior may make messages that originate 
elsewhere seem as though they are coming from your users.  ..and the message 
content usually doesnt vary much (if at all). probably already thought of this, but i figured it might be worth 
mentioning anyway...
