Hello, I would appreciate any help on a problem that's likely a no-brainer to this community. I'm just a bsiness guy - not IT, setting up a small business using SBS 2003 Premium Edition. I successfully installed it all, at least that's what it said... I added some a couple of test users, who have the appropiate tabs re: Exchange when I look at their properties. Problem is I cannot seem to send or receive email. If I send one of the users, or even the Administrator a message from outside I get: ----- Transcript of session follows ----- administrator@athand.ca... Deferred: Connection timed out with mail.athand.ca. Warning: message still undelivered after 4 hours Will keep trying until message is 5 days old -and then of course it gives up after 5 days. Any suggestions? Thanks in advance -Steve
