I’m using the Zimbra Collaboration Suite for some days now and I have to say that I’m really happy with it. The user web interface is just awesome, easy to use and I love the Ajax stuff. I’m also using it on my iPhone and it runs perfectly. There was just one thing which made me feel a bit uncomfortable with. After the installation the Webmail component was just accessible via HTTP which is not encrypted. During the last years I got some bad experience with other applications which needed to be changed from HTTP to HTTPS and this time I had a uneasy feeling but it was without any reason.
After some searching I found the command which helped me to change the protocol. First I logged into my Zimbra box and changed to the Zimbra user context. Then I used the command:

After restarting the Zimbra services with:
the server was ready again and the Webmail accessible via HTTPS. The command zmtlsctl can also be used to change back to only HTTP when using the parameter http instead of https. There are also mixed mode configurations possible.
The complete syntax for the command:
