This week my companies email account has changed from Exchange to Zimbra Collaboration Server due to my participation in an internal pilot program. This is great because I’m already using the Zimbra server and also the desktop client  privately for a while and I’m really happy with it. What I’ve never thought about before is [...]

For quite a while now I’ve tried to get Zimbra Desktop working with my Zimbra Collaboration Server (ZCS) but I couldn’t get it running.

It’s important that you have a valid A-Record and MX-Record for your Zimbra Collaboration Server. During [...]

For a long time I was running Mail Enable, a Windows based mail server application for my private emails. Mail Enable is free when you just host a few domains on it but the disadvantage for me was that it’s just offering plain email services like SMTP and POP3, no calendar or task management. Since [...]
