Bounced emails in MTA?

Crazybeaver

Hi,

I'm using our Sophos XG210 as spam protection for around a week now, coming from Sophos Central email protection.

Everything works fine except for a few bounce mails. These emails are bouncing but I don't really know why, I haven't really found a way to dig any deeper too. I've already whitelisted the domains+IP's of the senders but they still get bounced.

Does anyone have a suggestion for me?

    ADMIN Mar 23 10:52:26 [*]: [*] FROM = *, TO = *, SUBJECT = *, recv_time = Mar 23 10:52:21, size = 428657, status = Bounced,reason = SMTP Failure in DATA command.
