And if the customer specifically requests that YOU do not filter his email, or set up a system that allows him to see ALL email, even if ti is tagged as spam?
sell the customer a colo box or a virtual private server and have him do whatever he wants with it commodity / customer mailserver operations do involve filtering
provider, and they may all be very true, but it does not change the truth that a single false positive can ruin a business.
If you filter spam, return clear bounce messages that show why the filtering was done. Ideally return a url in the bounce message that links to a clear explanation + tells you what to do about it. And a response mechanism to handle false positive reports, that addresses these ASAP. Just for example (and never mind the content .. 127.0.0.2 is a generic address thats inserted in most blocklists) - http://spamblock.outblaze.com/127.0.0.2 Bad spam filtering is what gives all filtering a bad name ... what I would call the Wile E Coyote school of spam filtering. Like a trained mining engineer can use a fused bundle of dynamite to blow a hole in a rock - he'll blow up just what he wants to blow up, nothing else. Give Wile E Coyote that dynamite and ask him to blow up the roadrunner .. you know what happens next. -srs
