I have a similar box but currently ~1TB U160 SCSI Raid and with ~1700
users we have a default quota of 500MB. Some accounts however have quota
of ~2GB. I don't think there is a recommended quota size. It really
depends on what you are doing. Usually ISP and universities have smaller
quota than in the corporate world but you are free to do what you want.
IIRC Cyrus IMAPd has no problems with big quota.
