This list contains some things you may want to check before or after installing VPOP3 to make sure it's not going to encounter any common issues.
Because VPOP3 uses a database for data storage, it will perform badly on a RAID 5 or RAID 6 array compared to simple disk or RAID 1 array. We recommend installing it on a RAID 1 or RAID10 array.
There are many articles on the Internet about why using a database on a RAID 5/6 array is a bad idea, so we won't repeat them here. Basically, small writes are incredibly slow.
(Some of these can be performed before installation as well, but we've put them here, because you can do them afterwards if you forgot beforehand.)
