When TLS is not activated, mail is not received my the mail gateway encrypted, only unencrypted.
Whtn TLS is activated, mail can be received encrypted but, it tries to relay to internal mail server also with TLS, and when this failed it delays the mail 5-10 minutes. I tried to force unencrypted internal relay by adding the domain under TLS-policy tab with policy "none", but this doesn't change anything.
