Not sure if anyone has mentioned this, - a quick search did not flag it.

I used the older version of Qmail Rocks installation instructions on Fedora up to 12. Then decided it was too much trouble to keep up with the updates in Fedora, and at which time all internet references to Qmail Rocks for Fedora disappeared - the version I was using was really old anyway, and I had updated various components myself.

However, I then found this link: http://qmailrocks.thibs.com/

Which is an updated version (last update Feb 2011) for Debian. I actually installed it on Ubuntu Desktop 32 bit (64 bit fails).

The installation following the instructions was comparatively quick and easy and it uses RoundCube which to my mind is a less clunky looking Web interface than Squirrelmail which was used on the Fedora version.

Currently have a Dell Server set up and ready to switch over. Looks clean and stable.

Good luck.

Some interesting points raised.

Of course, it may have been you who originally asked this question Google in the first place...
