i like to use webmail over https because i only have one ip address for my web server and mail server which are on separate boxes. to set zimbra up to use https instead of http use the following command
zmtlsctl https
zmcontrol stop
zmcontrol start
after you restart zimbra, you can now log into zimbra using https://mail.example.com
if you’re like me, you’ll want to use your blackberry with your mail server to send and receive all of your spam messages. by default, zimbra collaboration suite is setup secure enough that a bis (blackberry internet service) server will not be able to connect to your box and push email to your phone, but there is a work around.
warning: the following howto will cause your passwords to be sent as clear text which is not recommended
1. log into the admin page by going to https://mail.<yourdomail>.com:7071
i’m a zimbra fan and use it on a daily basis for my personal websites and my consulting business. i love the fact that they brought their web client to the desktop and that you can create and send emails while offline. one issues i had when installing the zimbra desktop client, was on reboot of the system i would get an error stating
the connection was refused when attempting to contact localhost:7633
i did a search and found out that it was caused by the zimbra service not starting upon login. to fix this, you simply need to add the following command to the session manager in system > preferences
/home/<user>/zimbra/zdesktop/zdesktop start
or
/home/<user>/zdesktop/zdesktop start
and thats it. you can download zimbra desktop from here.
