Sometimes I get an sent email that hasnt got the from: in the header in outlook.


Completely empty. Then I delete all of the blocked IP's in a table and the the from: show up again like nothing happend when sending another mail.

Anyone has any clue on how to troubleshoot this? Its like its triggering data from somewhere that I havent got a clue of where is.

Fiddler gives me nothing.
