Sending mail in outlook fails, but telnet to SMTP server works

Yesterday, several machines at one of our locations stopped sending emails.  Outlook keeps saying "sending 1 of n" and will not successfully send.  I set up an account in Outlook Express on the server, and it is able to send just fine.  I have disabled anti-virus programs; Windows firewall is turned off;  There aren't any other add-ins that would interfere.

BUT, if I telnet into the SMTP server and manually type in the commands, I am able to send a messages - even from the machines in question.  Therefore, I know it's not an issue with the SMTP server.

Does anyone have any advice?  Thank you.

Sounds like a routing issue;
try deleting and recreating the user's profile and see if this resolves the issue
hope this helps

ah ha.  That was the solution.  Strange how it occurred on several workstations at the same time.
