Thanks for the endorsement! I sometimes feel that the multi-instance aproach is under-appreciated, and new users are at times reluctant to try it, fearing it will more complex. I am glad to see that at least one is brave enough to take the plunge. I guess it takes a mix of requirements that are in combination complex to implement without getting in each other's way, but can be cleanly separated into distinct groups for separate message flows (null client, inbound mail, outbound mail, ...). If that's your situation, don't be unduly afraid of multiple instances, divide and conquer. -- Viktor.
