Spam? Hacked? Spyware?   
We have users receiving messages that are not addressed to them.  It comes in 
a spam mail and has valid addresses to other users in the mail system but it 
is NOT addressed to the person receiving the mail. 

Thought it was just a BCC but thats not the case.  SMTP header info would 
normally show your own email addy if you're the BCC recip.  This is not 
happening.

How are these mail being sent to these users?


Thanks,

Tom

They are just being BCC'd. BCC recipients do not show up in the SMTP
headers, even if you are a BCC recipient.

Gary,

*They are just being BCC'd. BCC recipients do not show up in the SMTP
 headers, even if you are a BCC recipient.*

I used to think the same thing but after testing I found out that that is 
not the case.

 (iPlanet Messaging Server 5.2 HotFix 1.25 (built Mar  3 2004))
 with ESMTP id  for 
tmccarroll@dc37.net;


This from the SMTP info on a BCC to tmccarroll@dc37.net.

I still think its spam and could be bcc's.  I'm just trying to make sure.

Properly configured mail servers don't display who was bcc'd. You were being 
bcc'd. Whose server is it you're looking at here?
