Krishna- 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 infected. 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). ..you probably already thought of this, but i figured it might be worth mentioning anyway... -matt -- __________________________________________________________________ Matt Dillingham Systems Administrator II University of Michigan, Bioinformatics > Krishna Kumar wrote: > > http://www.MSExchange.org/ > > > Dear all > > Some of my users are complining that their receipients(external only) > are getting mails which are sending to them, multiple times.
