I’m trying to configure my MS Exchange Server 2003 but have run into a problem. I’m able to send and receive mail internally without issue, however am only able to receive external mail, but not send. I have comcast as my current ISP, and have read some articles on port restrictions placed by comcast. I’ve tried changing port 25, to the reccomended alternate of port 587, however neither one seems to correct the problem. If anyone can offer any suggestions, it would be appreciated
