Which fs for storing mailboxes?

[Pandu Poluan]

Hello list!

We're going to deploy Axigen for our subsidiary company's email system.

Now, I want to split the storage into 4:
  * Boot : ext2
  * Swap
  * Root : ext4
  * Mailboxes : ?which?

The question: what filesystem should I use for the partition
containing the mailboxes? Ext4? XFS? Or something else? What would be
their advantages/disadvantages?

FYI, the email server will have 40~50 simultaneous users, traffic will
be relatively light (I don't think there will be more than 30-40
emails per day for 90% of the users), and the emails mostly are
mid-sized (100 KiB ~ 1 MiB, occasionally (less than 5% of time) 2 MiB
~ 4 MiB).

Thanks in advance!

Rgds,
