I'd recommend mdbox as well, with a healthy rotation size. The larger files won't increase IMAP performance substantially but they can make backup significantly quicker.
I'm considering migrating to mdbox... wondering what you consider 'healthy' rotation size.
I generally try to avoid changing defaults whenever possible, [...]
I am running "mdbox_rotate_size = 100m" for approx. a year now on a small server (a handful of users, only). All mailboxes are around 1G each with a lot of attachments. I never had an issue so far.
Don't ask me why I did chose 100m, I cannot remember ;-) Ok, if one of such mdbox files will become corrupt, I will loose a lot of mail, but on the other hand I am running two dovecot servers in parallel (replicator/dsync) and I do take hourly snapshots (ZFS) of my mail storage file system as well.
