can't connect to exchange server using IMAP on Fedora Core Linux

What message is displayed when you telnet to port 143 of the Exchange server?

Are you aware that your username is of the form:

\\

Kind regards,

telnet didn't work but the port is open even with an xp pc can't connect.
error connection denied.
DC is a windows 2003 server running basic firewall.

I can telnet to the exchange it says ready what can i do next?
when i go to the linux client it says bad username or password, but i verfy it's a valid username and password, any settings on the linux client that have to be set?

If you got your telnet session going to the IMAP port, you can terminate the session by typing in

1 logout

As the second answer suggests, you may have a problem with the username in your email client settings.

okay thanks guys for the tip, i had to lookup how to get in the IMAP telnet i use, a01 login (email address >myname@mymail.com) i was putting my regular windows ID and PW then was able login so i use that info on the settings and able to pass the password screen i can send mail but the funny part i don't see any mail in my inbox on my linux pc but i can see my emails on my windows pc, i reply on my windows pc but i don't see them on my linux pc

sheez....
now i played with my inbox on my linux pc and now able to see my inbox but i keep getting errors unable to relay when sending outside email, do i have to enable relay on my exchange? Is that kinda risky to enable relay on the exchange server?
