We run Cyrus on ext3 under Debian Linux without complaints here.  We have 
approximately 35000 mailboxes/users split between 2 backend servers. 
Each backend server is connected to an EMC Cx500 SAN (no shared access or 
anything fancy) with 800GB of mail spool each.  The commands used to build 
the filesystems were:

   mkfs -t ext3 -j -m 1 -O dir_index /dev/sdb1
   tune2fs -c 0 -i 0 /dev/sdb1

The filesystem is mounted like so:

   /dev/sdb1    /private     ext3    defaults,data=ordered,noatime   0   2

If you want more information, just ask.  :)
