i went to one of the windows 2000 workstations and tried to configure outlook express to use my linux box as incoming and outgoing server.

i put in the user test and pop3 and then i "auto test" the config

the outlook sees the system and both of the (smtp and pop3) as open but then on the 4th step it cannot log on into pop3 server and 5th step cannot sent email throug smtp server...

what could be the problem
Are you sure you have the correct mail servers? Does your SMTP require authentication? It's usually mail.isp.com or pop.isp.com (port 110) & smtp.isp.com (port 25) have you tried sending yourself a test message? Do you have any current antiviruses running while your sending/reciving e-mail? Is their anyway you can display the Outlook express error code?
