I plan to use a SMTP Archiving feature in my archiving solution (non Microsoft). I wish to send a BCC copy of every message to a particular SMTP server (installed on archiving software). In Exchange 2003 there was a BCC journaling feature that could be enabled in a registry. Is there any way to direct all messages, external and internal, to a third-party SMTP server on Exchange 2013/2016? On that separate SMTP server I have an archiving software that can capture and archive incomming messages. I'm not able to use standard Exchange Journaling, since I have no licenses to integrate my currect archiving solution (non Microsoft) with a Journal Mailbox.
Any ideas? How to configure it in Exchange?
