[Dovecot] maildir vs mdbox

[Jean-Daniel Beaubien]

Wow, incredible response time :)

I have 1 more question which I forgot to put in the initial post.

Considering my use case (small number of accounts but alot of emails per
account, and I should add that they are mostly small emails, most under 5k,
alot under 30k) what mdbox setting would you recommend i start testing with
(mdbox_rotate_size and mdbox_rotate_interval).
