Hm, I don't like Horde... It has too many dependencies and is hard to set up. Other webmailers like Squirrelmail and Uebimiau are much easier to install.
How to for Horde/IMP I am familiar with Mailtraq a commercial version, which is based on Horde. I do not like Mailtraq/Horde either and i prefer IlohaMail, which is much easier to install and has almost the same features. I have a lot of things on my to do list, but i will try to write a setup for Horde on my testing server, when i have time for it. I do not know if i will succeed. As Falko said: It is hard to setup. I know this, because I've tried it before.
Horde Groupware Webmail = easy to install Hi, I'm new here. I used the perfect setup for CentOS 4.4 for setting up my VPS, great initiative Now I just installed Horde Groupware. I couldn't have been easier! Dependencies can just be installed with yum or pecl, giving no problem at all! I suppose it doesn't matter if PHP was not compiled with the needed dependencies, while installing it afterwards? But just give Horde a try, lovely program Edit: Don't forget to point to the sendmail wrapper if using postfix (/usr/lib/sendmail.postfix)
i vote too for Horde Groupware Webmail Edition its very simply to install & use http://www.horde.org/webmail/
