Kevin,
sorry forgot to add that info.
Brightmail Gateway Version 7.7.0
Using Exchange 2003
I have sent an email to the end users IT department asking what they are using.
I do know that it is not every email. but atleast half the corespondence. and they seem to be when my users reply to the external user.
the external user is in europe.
also the emails I have on this show an email with just the outgoing legal disclaimer we attach. Then the actual email is an email attachment.
