Hey Guys, Im trying to send mail via smtp from a none domain machine to one of our smtp servers. its running exchange 2003. I have the IP address addedinto relays but it still doesnt seem to work. I can tellnet on port 25 using any domain computer. Its on the samegigabit switch and the same subnet. I can ping the machine no problem. I can telnet in on port 80 and 443 but cant on 25. If i attempt to telnet from this machine I am unable to get in. What am I missing? Thanks for any advise. Regards, Tom

This was due to mcafee port blocking on port 25! Thanks anyway!
