Squirrelmail was getting getting on my nerves.
Sadly its development seems to have stagnated in the last few years. A pity really, it wasn’t bad software.
I hadn’t used IMP on the Horde framework in a couple of years so I thought I would give it a try. The (old) version in FreeBSD’s ports collection was buggy and that gave me some trouble at the start, but after I realised and got the latest version installed down installation was pretty much a breeze. Considering how much code there is in Horde in general, and how complex said code is, the speed of the applications even over modem links continue to amaze me. Those guys have talent.
At the same time I upgraded to WordPress 2.0 I wish I could make my software look as good as these two.
