how to configure email server
here's the problem
i have a mandrake 9.2 box on a public IP *.*.*.100
then i have a network of windows 2000 systems in 192.168.111.* range hidden behind a public router w/ *.*.*.98 IP
i want to use the mandrake box as a email server for incoming and outgoing mail.
the smtp port was already open when i installed mandrake so then i manually installed imap rpm after which the pop3 became open
when i say that these ports were open i mean that they were visible on a nmap scan... I DON'T KNOW IF THEY ARE FUNCTIONING PROPERLY!
then i created a user "test" and added him to a "mail" group on the mandrake system.
then 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
