Country Blocking exception for SMTP Proxy possible with UTM 9.5?

Alexander Busch

For security reasons, I'd like to use country blocking to block some incoming connections. In connection with Mail Protection I am not able to define a working exception for SMTP.
Attached a screenshot of the exception to be defined, here only as an example:



In Country Blocking Traffic from Indonesia is blocked.

Has someone already managed to exclude the mail proxy from country blocking? I would appreciate a hint.

Best
Alex

    Nope. I want to block connections from an country (here for example Indonesia) except SMTP. And using the SMTP Proxy of the UTM, called mail protection.

    Tested with a telnet connection to port 25, of course coming from an IP which is classified to that country.

    Worked with ping / ICMP very well.
