Windows Server Forum / Exchange Server / General Topics / May 2005Spam? 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 mcdonnell http://turbogeeks.com We have users receiving messages that are not addressed to them.

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 <0IGO001R5TPV28@mta3.srv.hcvlny.cv.net> 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. > They are just being BCC'd. BCC recipients do not show up in the SMTP > headers, even if you are a BCC recipient.

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? >> They are just being BCC'd.
