Benifits of ReiserFS?
I know that a maildirs run better on a reiserfs partitions, will I feel this benifit under UML? Has anyone done this and found an improvment?

You can get reasonable response times to many files in one directory with ext3 and resier. If it aint broke then dont fix it.
May I suggest one thing though… If you want to move to ReiserFS, format a partition that only holds your mail directories, and keep backups like you should be in the first place. ReiserFS seems to have a lot of disappointed users from broken filesystems (I've heard a lot of comments about fsck.reiser making people's partitions un-recoverable).
I thought I would give all the warnings first, but I am a fan of ReiserFS, and have not run into a single problem in the 3-4 years I've been using it. I've even written a GUI frontend to a reiserfs library for reading ReiserFS partitions under Windows some time ago that I still use to this day. Then again, ext3 has never failed me either, I just like to think towards the future of Reiser4, and the million of possibilities it opens up as a filesystem.
I haven't tried ReiserFS 4 so I don't know if it is more reliable than prior versions.
I tried JFS (from IBM) and have been pretty happy with it. Seems very CPU-friendly. But I wouldn't recommend it for your scenario because JFS is relatively slow when it comes to dealing with thousands of files within a single directory (in all other aspects, it is very fast).
You might want to look into XFS if you really MUST improve performance. I haven't tried it yet, but everyone I know who has tried it seems to be quite happy with it and there are fewer unhappy users. It uses substantially more CPU than JFS, but is pretty fast.
If you can, just stick with EXT3. Good luck!
What happened that caused your data corruption? How could you tell it was Reiser and not your HDD?
I'm just curious. I have no feelings about which FS is "superior" - I've always just used Reiser because I've never had a problem with it.
