I've have a couple 5.6 & 601 E-Smiths set up for backup MX services, ClamAV & SPAM filtering (thanks to Jesper K's great addons) and was planning on upgrading to the 712 with its built-in SPAM & AntiVirus.
The 5.6/601 machines have the qmail/control files set to store/scan/forward email to the downstream destination servers, it all been working great for years.
I've set up a 711->upgraded to 712 server and stuck that in front of the existing set of SME filtering servers for a test domain and it is resulting in no virus filtering, no SPAM filtering. That and almost zero message header logging for audit/tracking purposes. SPAM and virus are being reported by the downstream machines but overlooked by the 712 host.
The qmail/control approach was used to accept the otherwise invalid domain traffic and to direct the output to various recipient servers. Do I need to forfeit that approach and use the Delegate Mail Server + Virtual Domains?
These servers have no users/ibays/domains and are purely relays.
Any enlightenment greatly appreciated.
