>>Email Relaying Restriction
>>
>>Over the past few days, our systems have been used as a relay host for
>>subscribers of other services (in the most recent case - CompuServe) to
>>forward out hundreds of Spam messages. This action has put a tremendous
>>load on the servers, and generated hundreds of failed attempt message to
>>the administrator (me!).
>>
>>We are running the latest release of Post.Office (v3.1.2) and it offers
>>features to block/eliminate this type of activity (at least they claim this
>>in their adverts). I have reviewed the options available, and there are
>>many - but I have not quite figured out the best solution for our setup.
>>
>>What I think is the best solution, which I think would solve my problem is
>>as follows:
>>- Allow mail from ANY outside domains to flow freely into domains hosted on
>>our mail server. This would mean blocking any mail not for local domains.
>>- Allow mail from ANY IP addresses on my local domain to flow out freely.
>>
>>This sounds like a simple solution to me, but I cannot figure out how (or
>>even if this is possible) to do with Post.Office. Has anyone any experience
>>in this type of configuration with Post.Office?
>>
>>My second question, also around Post.Office, is whether I can have all
>>messages which go to the Mail Administrator (error messages) go into a NUL
>>device?? I really don't want to have to look at all the error messages on
>>the Mail Administrator account daily, nor do I want to be forced to clear
>>out message from the "Deferred Mail", "Handle Error Messages" system
>>administrator option.
>>
>>Any advice on these situations would be appreciated.
