I've had an influx of a few users who are receiving administrative notices from other servers that the emails they are sending out are infected with Klez. As you know Klez works by attaching to the "To" portion of the email ANY email address it finds in the addressbook of the infected user. So that it looks like it's coming from a different person that the one whose really infected. I've told my users that there systems are clean (I've run 2 different Klez detection utilities to confirm this) and that there unfortunately isn't anything I can do as the infected person could be anyone who has ever sent them an email address. Am I correct in this regard? Darien Allen Center for Poverty Solutions --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
