Hi Wietse, thanks for your kind reply...:-) ! You're right...
- We currently have a setup where all mail from R&D internal->external is send to my mailrelay in a specific site, as our_isp_relay only allows us to send from there to their mailrelay - no restrictions (this is not our primary mail). - Our_isp_relay has already blacklisted my mailrelay twice, caused by reputation based filtering - no spamming occurred though (all known domains at-least...), but the number of mails was rather high... - We are about to send monitoring alert through my mailrelay pretty soon, and therefore I would like to avoid spam filtering if possible - but saw domain-whitelisting as a solution to limit damages to a minimum if a host goes hostile... - Our Printers are also on the R&D network and they need scan->email functionality, so I still need to allow printers to send to anyone. - 99.96% of mail going through my mailrelay goes to our own official mailboxes, so my thinking was to route all this directly to our official mailserver and get my mailrelay whitelisted there (so no spamfiltering is done on mails from this IP)...
