Hi all,
I do have a nooby question [[:)]] I recently installed an exchange and put that server behind the Sophos UTM 9. For some old (historical) reasons there is a Postfix reverse proxy between the Exchange and the UTM.
To the UTM config:
- SMTP Proxy is disabled (due to those Postfix reasons)
- The Exchange server (internal IP) is listed in the SMTP-Server List (IPS -> Tab Advanced)
- The Exchange Server is protected by Web Server Protection and there are some NAT Rules für IMAP etc.
The Point is, that I had to disable the IPS for the Exchange Server because the IPS blocked every E-Mail with an attachement.
Did I missconfigured anything?
Best Regards and many thanks [[:)]]
