Sophos does not send a quarantine digest if an outbound email is quarantined by antispam. I checked antispam engine for outbound traffic by using the gtube string. My Outbound message has been quarantined as expected. I am not notified about that issue. So my users are not able to recognize that important Business email are not delivered.

I opened support case 03082732 for that behaviour. They told me:

“Regarding the quarantine summary digest for the outbound emails, right now this feature seems not be supported on the XG.”

Please improve quarantine digest.
