Re: [CentOS] Email/GroupWare Suite
Have you looked at the SME server disto from http://www.contribs.org? It installs as an appliance-like setup managed through a simple web interface. The code is mostly centos and includes hoard webmail running over dovecot with maildir storage out of the box. It doesn't have a shared calendar or other groupware components in the base setup and it is somewhat difficult to modify the already-customized configuration but there are a number of contributed add-ons that might provide them. Unfortunately the site seems to be down for maintenance right now so I can't check on them. Anyway, for a few hundred people, the setup really is as simple as answering a few questions and adding the users and it can also provide file/print/web/vpn services. -- Les Mikesell lesmikes...@gmail.com ___ We have been using SME server 7.x for a long time now and I'm very happy with it. The installation is very straight forward and it does standard email out of the box. To get groupware, you need to install the egroupware / phpgroupware addons and then you have a good groupware as well. Support is generally good, but SME still runs on CentOS 4.7 and not 5.x They are working on SME 8.x which runs on CentOS 5.2 though, but there's no stable release yet. -- Kind Regards Rudi Ahlers ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Email/GroupWare Suite
We are a public k-12 school and are looking to migrate to a groupware style system for out staff to collaborate better. Currently we are using Squirrelmail/postfix for email. Does anyone have any recommendations/opinions. Any input would be greatly appreciated. Thank you I would stick in a suggestion to look at Scalix. Not free at 300 users, but it does run nicely on CentOS. Integrates well with Outlook and has a very nice webmail front end. I would be careful with Scalix. My son used to work at a place where they went with Scalix for 300+ users. The day to day maintenance on it can be a real bear. When you have a real problem that requires support, Scalix support is less than helpful. He left that job for another but still keeps in touch with his old boss. The old boss has told him that due to the Scalix problems they are budgeting for replacing Scalix with Exchange. On the other side of the coin, when it works, it works well and integrates well with Outlook. It is just overly complex under the hood. This is one of the beauties of OpenGroupware - it's just PostgreSQL and the filesystem. Simple and clean; PostgreSQL 8.3 performance is very good. And you just reuse whatever SMTP/IMAP architecture you have or want, this a strong bias towards Cyrus (of course). That is how it should be, IMHO, subsystems should be loosely coupled; but it does make it more difficult to implement some features. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Bo Lynch schrieb: Should I be concerned with the Licensing structure down the road? Meaning in your opinion do you think that zimbra will close its door on the open source model. The chance is always there. I come from the BSD-world, where this is happening regularly (or actually designed to happen). Think about it: if outside contributions are minimal and lot's of people offer services around the product without some sort of revenue-sharing, the product will die one way or the other. This is what happened with Nessus. Zimbra is way too complicated to survive as a pure non-company-sponsored GPL OSS-project. It's in the same league as OpenOffice IMO. Do you think OO would exist without SUN sponsoring most of the devs around the main project? In the BSD-world, it's a valid business-model to create some fork of a technology, commercialize it and later release most of it back into the tree. Even in GNU-land, you have more and more GPL-products with proprietary extensions for paying customers. What I want to say is: I believe Zimbra chose their license not because they wanted to cheat, but because they actually wanted to be able to keep stuff open-source while at the same time ensuring the company's commercial viability. Just don't want to demo something get everyone excited about using it and have to migrate to something else. Well, that's your choice. AFAIK, apache also has a BSD-style license that would allow it to keep the source for themselves - doesn't stop you (or most everyone) from using it, I assume... What happens to a product over one, two or three or more years is anyone's guess. Certainly, yahoo + zimbra have plans (that they don't want to share with us, most likely) - but wether these plans can actually be put into working is another question. Release 5.0.x is out now and will be supported for quite some time. Release 6.0 will arrive sometime next year. No change in license is visible for it now. I think Zimbra has always been profitable as a company, at least before the Yahoo! acquisition. If this continues, I don't see Yahoo making lot's of changes.

We have a mixed network and use Active Directory as central directory service. I had no problems to bind SOGo to ADS. But it should be no problem to use OpenLDAP or similar.

I've been evaluating some packages for my employer the last few months. The two products I have narrowed it down to my needs are eGroupware and Zimbra. So far, I'm leaning towards Zimbra, because it seems to offer a nice e-mail system with an easy to use interface for users. There is a community edition and a commercial edition. http://www.zimbra.com/community/downloads.html I too am currently using Postfix and Squirrelmail, and would like to keep using Postfix as the primary transport system. There is a way to configure Zimbra to act as a secondary system forwarding mail to Postfix, but I can't find the link right now. There are also methods to migrate to Zimbra from Squirrelmail using some imapsync scripts to migrate the mailboxes. By itself though, it seems to have a nice and powerful mail system with all the features of anti-virus, spam, etc. eGroupware works great too, so make sure you check it out, but I'm thinking of leaning towards Zimbra for my needs. http://www.egroupware.org/ Check them out.

We looked at PHPgroupware a long time ago (2003?) and it did have allot of features but not a very strong core and some parts of it seemed unfinished. We also were considering throwing in the Open Source towel on groupware and going with Notes. Fortunately that was the moment that OpenGroupware was released as Open Source, we've been using that ever since and are very happy. It is fast, minimal requirements, uses Cyrus as the mail store (*very* hast and feature-ful), and has a solid set of core features. The WebUI certainly isn't the sexiest but it is robust and has a great XML-RPC API.

Re: [CentOS] Email/GroupWare Suite
For a completely /different/ idea... I know several nonprofit and not-for-profit groups who coordinate their email and activities using a combination of GMail, google calendar(s) for scheduling, google apps for shared documents, and google group(s) for message board functionality. You can pull all this together with a google website, and put it under a domain name. The advantages of doing it this way are no costs at all, no hardware, no hardware maintenance. you just have to figure out how to put the google pieces together and teach your users how to use this mashup you've created from the various google pieces... the downside is that google is running everything, and you're relying on google goodwill to continue running this. your files and data are stored on their systems so you're subject to their privacy policies. and, of course, if your internet link is down, you'll have no access to any of it. otherwise, um, if you really do want self hosting... pick your favorite email server (postfix, sendmail, etc), use cyrus imap, let your clients use any imap email app they prefer (Mozilla Thunderbird, Microsoft Outlook or Live Mail, etc) and use openLDAP for a directory service.A wiki like DokuWiki can provide for group shared stuff...add in a calender server (webDAV wth iCAL files, or similar) that can be used with Thunderbird's Lightning Calendering plugin, and you've got quite a bit of groupware functionality right off the bat, including meeting invitations. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

We are looking at zimbra and using at least two machines utilizing GFS and our SAN so we can withstand a failure. We have around 75 users but I am not willing to have email down due to a single machine failing. (Btw, these would be virtual machines running on xenserver) Seeing as you are in education, if you are looking to actually pay for licensing a product and are actually interested in Zimbra, take a look at their hosted model. It is only for educational institutions right now (not that I know if they will make the offering more widely available) and may fit the bill even more by not having to manage the hardware. My biggest concern is the long term viability of zimbra with the possibility of MicroHoo or someone else picking up Yahoo in the future. I don't want to start something with that one, but for a business this is definitely a concern. I believe some of this has been addressed in their licensing language and there is always the the GPL version which would probably survive for at least a short while. Andrew We would definitely be looking at a app for free in other words zimbra's open source release. We are planning on using existing hardware that we have. Currently we are running CentOS 5.2 with Pentium D 3.2 with 2gb ram and 2 500GB SATA drives in a RAID. The motherboard that we have will support a quadcore xeon if needed. Are setup now has no probs but we are only doing basic email and calendar within squirrelmail itself.

Would you like to do support for your product that relies on a dozen or more external other products (that aren't maintained in most Enterprise Linux distributions anyway) when any of the vendors you support the product on can introduce a patch anyday that changes some stuff only you need in your software - and now you have customers all over the world phoning you why your P-O-S-software stopped working out- of-a-sudden. They have to maintain their own releases. If you are forced to use them then how delayed are the releases. There's a new release every couple of months. See http://pm.zimbra.com It's not that bad. If there is some serious problem, they provide extra hotfixes, too. It's (well, supposed to be) a turnkey-product. At least, the pay-version is.

These guys are very generous with pricing when it comes to educational facilities in case anyone is looking. You can still use it. Just not on the Zimbra-server. I'm actually glad they don't have so many use this instead of that stuff. Just more stuff that could go wrong and that nobody QAs anyway.

Re: [CentOS] Email/GroupWare Suite
otherwise, um, if you really do want self hosting... pick your favorite email server (postfix, sendmail, etc), use cyrus imap, let your clients use any imap email app they prefer (Mozilla Thunderbird, Microsoft Outlook or Live Mail, etc) Agree strongly with PostFix+Cyrus. It is a very solid e-mail platform and it provides delayed expunge and unexpunge (data retention), shared folders included shared seen state, full-text indexing, and quotas. and use openLDAP for a directory service. I'd discourage this. LDAP is great, and OpenLDAP is a solid DSA, but LDAP makes a miserable groupware platform. No client other than Evolution supports updating LDAP, every other client is read-only. And no clients agree on schema. It's pretty awful for usability. A wiki like DokuWiki can provide for group shared stuff...add in a calender server (webDAV wth iCAL files, or similar) that can be used with Thunderbird's Lightning Calendering plugin, and you've got quite a bit of groupware functionality right off the bat, including meeting invitations. One needs to carefully define what you need and what features you want. Calendaring is very vague. Do you need resource reservation, conflict detection, participant roles, etc... For addressbooks GroupDAV is reasonably supported by most clients at this point (including Thunderbird). Calendering is more complicated. Most importantly, you *MUST* have GroupDAV or CalDAV for group calendering/collaboration - iCalendar is *not* a groupware solution, it just doesn't work for technical reasons. -- Adam Tauno Williams, Network Systems Administrator Consultant - http://www.whitemiceconsulting.com Developer - http://www.opengroupware.org ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I would have to agree here too. It can be a pain if you would have to maintain all the dependencies on a boxed system like this. There are plus and minuses to both. This is much like VMware's model for their Infrastructure software. (Yes, I know I'm comparing apples and oranges, but am using it as an example.) They are running on a RHEL base, which they maintain. You can't, or should I say you shouldn't, install, modify, or fiddle with any of your own packages, because they are supporting the actual OS, all the dependencies, as well as their own code. This is a plus because the project X maintains the patches, updates, bugs, etc. I think you could argue this as a benefit, or a nuisance, but if you're not looking to have to maintain separate pieces of a system, then it would be a benefit. If you have the time and resources to maintain them all separately, then you have the choice of choosing something where you have more control. If I'm not mistaken, I believe Zimbra tells you right up front that it should be a dedicated server for just Zimbra. It's purpose is exactly that, and you get what is advertised. I guess this is why mailing lists exist, so everyone can give their opinions and experiences as advice. Ultimately, you choose the project that you can best maintain given your time and experience, and what best meets your needs. My two cents anyways.
