cyrus and 500k to >1M mails per inbox

we have a customer running cyrus imap on RHEL5 cluster with a few thousand
Every single mail is sent to a second host acting as a read-only archive (all
imap acls set to no write access).

The plan is, that all mail on that second host is kept for a long time.

After some years, old mail will be purged automatically.

It's quite likely, that these mailboxes will grow to 500000 or even more then
1M mails per mailbox.

Does anybody have experience with such big mailboxes?
The filesystem is LVM with ext3.

With best regards,
