we gonna install a Suse webmail server in a just few steaps, firts of all we install:
-Apache2 by yast
-Cyrus imap pop3
-Ldap by yast too
-then we go to network services in yast, and we install mail server, that is the tool who is goin to config the webmail server with postfix cyrus and ldap.
-we can allways install openmailadmin and mysql to administrated cyrus
-then to have a webmail client we can use squirrelmail and install it into the web directory.
to config squirrelmail, we go to the squirrelmail config folder and we do ./config then the config window will show, after that, we choice option D then cyrus for autoconfig.
at this point we allready have a webmail server up and runing
and thats all, i hope this can help to set up a fast webmail server.
