Possible mail relay

Hi team
Hi community
I have to deal with the "Possible mail relay" issue on the Gaia R81.10 security gateway and management server.
The service is detected by testing tools as "220 CheckPoint FireWall-1 ESMTP server". The ports are high, >33000.
Could it be a false positive? Or should I find some ESMTP settings via expert mode?

I would start with checking out $FWDIR/conf/fwauthd.conf

It propably has a line like:

2525 fwssd in.emaild.smtp wait 0

Yes, you are right
What changes are required?
Are there "how to" for fwauthd.conf?
