W2K Server 2k w/sp3 Exchange 2000 w/SP3 I can't get my exchange server to receive any mail from the "outside". I have my mx records set up internally, I've checked to ensure that my ISP isn't blocking port 25, I can send mail from the "inside" with no problem, I've forwarded port 25 for this server, so I don't know what else to do. Can anyone assist me with this? I've had this problem before in the past but don't think I ever resolved it. My domain name is nubiint.com and my mail server is mail.nubiint.com, or this is what should show if someone tries to check it. Any help is appreciated.
