It's not good to try to run other things on the same server as the zimbra box, but it runs fine in a VM and then you can run other VMs as needed. The only thing you really have to be aware of is that Zimbra really wants it's own server. Yahoo is fortunately one of the companies that still actively supports their OSS version. The cold hard truth is that if an open source application becomes very popular and works well as in the case of things like Zimbra, VMware, Xen, etc, then sooner or later someone is going to take it commercial. If the application works for what you want to do and you are lucky enough no to have topay for it, what do you care what the licensing is unless you are going to modify and redistribute it? Are you? If not, don't worry about it. The GPL as of late IMHO has become rather restrictive, but that's just my opinion. It just works.Īs far as the GPL goes, have you ever actually read it? I guess of you are a pureist then it's for you, but I much prefer the BSD style licence myself. It is absolutely rock solid and feature rich and requires very little maintenance. In fact, some features in the commercial edition still come from the OSS edition. It is absolutely not crippled in any way and continues to be developed right along side the commercial edition. I am an independent consultant, and I have several commercial customers using the OS edition of Zimbra. I have always gotten my problems solved there, almost always without even posting. The community is actually much better than at least half of the OSS community support, and I would say it's right up there on top. Zimbra has a very vibrant, active community and help is only a google away in most cases if you need it. You are totally wrong about the community support as far a s Zimbra is concerned. If horde is able to give me both webaccess to email/calendars and provide the same services for evolution/kontact I'm happy.Ĭitadel is just not what I'm looking for. Haven't looked at it as a complete solution, only in conjunction with a server like Kolab. It is getting complicated when adding calendar functions, tasks and shared addressbooks.

Most groupware systems are built on top of postfix and imap/pop so mail is not that difficult. For every simple app needed in a business system there is a good GPL alternative, but for groupware it's just not that simple. bootstrapping the system results in numerous errors, since intrepid uses the new online configureable slapd and AppArmor prevents access to files that the kolab_bootstrap is trying to use. I've tried to get Kolab running, but that's quite a job. The community support of those products is not what you see for truly GPL apps. I'm struggling with the same question, except that Zimbra is out of the question since it is not GPL'd.
