Outbound Email Message Data is Being Re-written (Not Message Header)

Hello; I have an outsourced IM archival system, data from IM sessions are sent to this system for archive via email. We select an IM message for un-archival, which is then emailed to us. The problem I am having is that even prior to arrival at the IM archiving vendor, my IM message has alread

How Can I Wipe Out Emails From Specific Sender

OK, now more.  Apparently there is a problem with one of my users who is constantly being spammed by a specific remote sender.  The remote senders email is always the same and somehow gets bounced for days in between my postfix server and my exchange bridgehead.  What can I do to just delete it

I am seeing a few spams coming through with a from address (seen on my postfix logs) that does not match the "From" address shown on my users Outlook. In fact my users are seeing a "From" address as their own, something that my postfix server currently does not allow using mynetworks and permit
