I have not used SoGo yet, but I have read good things about it from many admins. It is probably the only one free/open-source solution which works well with Outlook sync and with Thunderbird/Lightning sync. I plan to try it out soon. Read this thread too: http://www.mail-archive.com/dovecot@xxxxxxxxxxx/msg49002.html I have used Horde (in test mode, not in production) and it is good, but we had various issues, esp. when working with mobile devices. A bit complex in configuring / maintaining. We have also tested briefly FengOffice, which is slightly different: a groupware application, but it offers a web-based mail client with the ability to define multiple accounts. Other free groupware projects incorporating mail functionality: kolab, egroupware etc. We are currently still using SquirrelMail. I hate the GUI (aesthetically), but it works well and there are plugins for about everything one would ask. If only someone could create a nice contemporary GUI (HTML 5) for it! If someone wants Outlook / Thunderbird sync functionality, I would suggest starting from SoGo (even though I have not tested it yet). There are other open-source systems too which are not free: Zarafa, Zimbra, Open-Xchange etc. Nick _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
