We have been advised by our mail service provider that we are generating a "mail loop". This seems to occur when we receive mail addressed to an unknown e-mail address.
We are also informed that when we receive mail which is sent to an address list, with all of the recipients in the "to" field, Exchange automatically forwards these on to the numerous destination addresses.
Can somone please advise how we can deal with "badmail" so that messages sent to unknown accounts on our domain, are actually dumped into the "badmail" (its currently empty) directory, rather than bouncing it back as an "unkown recipient", and how we ensure that mail received which has a "list" in the "to" field, are not forwarded on.
OK, forgot the basics here, - we have sbs2000 - exchange v5 - sp4
