Hi
i am using a sophos spam box for protecting an internal mail server. Due to no facility to enable DKIM on the box, I have setup another Iredmail in DMZ for acting as a relay for all mails received by this box.

but whenever my sophos box relays any mail to iredmail server i get "client host rejected message in the maillog". i want to know if i can relay all mails coming from this sophos box to outside world while block any other source.

Secondly how do i relay all incoming mails from my dmz mailserver to sophos box for scanning and then to my internal mail server

i have already tried adding ip to mynetworks and iredapd and even to "sender_access.pcre" but it didnt help

Please assist

Regards
