I have been running my own patch for maildir support for a little while now.
I have yet to move to 4.30 from 4.14 so can't comment on that particular
implementation. But from my own usage of Maildirs compatibility with
CourierIMAP is the most important thing. You can't have exim using one
policy and CourierIMAP using another. For good or bad CourierIMAP doesn't
count tmp so Exim should honour that. I agree with another poster that
support for an option to count the Trash folder should be included.
Also it is important that the actual quota values are checked every time a
message is delivered so that dynamic quota changes can happen, the
CourierMTA behaves in this way. I believe from messages on the list this
does not currently happen with exim. My particular setup uses a lookup from
LDAP for this in both Exim and CourierIMAP servers, so which ever server is
manipulating the Maildir they can both trigger a valid rebuild of the
maildirsize file if the Quota values change.
Compatibility between how Exim and CourierIMAP use this file is the most
important factor. My 2p worth.
