SophosUTM can't be detected when spam mail is sent from the client added to Host-based relay.
Of course, it will be quarantined if the same mail is sent from the client which is not in Host-based relay.
I enable "Scan relayed (outgoing) messages". And I sent spam mail from the client allowed by Host-based relay (using telnet command). SophosUTM didn't judge this mail as SPAM by commtouch.
When the same mail was relayed as incoming message, SophosUTM judged SPAM. Therefore, I think that the SPAM check of outgoing message is not made correctly.
