Thanks for the replies, gentlemen.
John, that is the way I understand it. I believe Ed is on to something here. I changed the rules as (I think) Ed suggested, and I can now send mail outbound! However, inbound is no longer working. Now that I suspect that this is an Email Access rule issue I'm going to play around to see if I can find a combination that works for both inbound and outbound. For now I've got the following on the rats PC
CallSign = W4DTO
Access = Both
Email Filter = {blank}
CallSign = W4DTO-1 (this is the callsign I have on the rats PC)
Access =
Email Filter = {blank}
