how to configure Zimbra Desktop with POP or IMAP

[mkhurram92]

hi all there

i have successfully installed zimbra and everything is working fine....
now i want to give access clients to that Zimbra server so i installed Zimbra Desktop on every client computer.

It is only allowing me to configure it as none with port 80 just nothing more than this as shown below in image...
it is working fine in LAN but i m unable to receive mails from WAN.

i did not make any settings still to use IMAP or POP3. Both are already working so what i have to do now pls guide ???
