Is there any way to block emails from authenticated users that try to relay messages that have "mail from" different to the authenticated account?

I mean,

user1@mydomain.com authenticates against my KC server (mydomain.com) and tries to send a message that contains: MAIL FROM hello@otherdomain.com TO user2<_at_>secondomain.com.

I want to set that user1@mydomain.com is only permitted to send emails with MAIL FROM user1<_at_>mydomain.com.

Is it possible? I didn't find the way yet.

Yes, this is what Sender Policy feature in Kerio Connect is supposed to do. Check Security setting in Kerio Connect administration.
