Compared to IMAP-to-Maildir synchronization solutions like OfflineIMAP,
adding an IMAP server between the Maildir storage and the MUA saves

IMAP traffic is mostly text (beside message bodies perhaps) hence
compresses pretty well: enabling compression can save a great amount of
usage with regular INET sockets (type=imaps or type=imap).

SELECT (on both servers) a mailbox the current UIDNEXT or HIGHESTMODSEQ
values of which differ from the values found in the database (for either
server). Use the QRESYNC SELECT parameter from [RFC7162] to list
Performance is better for servers supporting the following extensions to

Using \fBInterIMAP\fR on two identical servers with a non-existent or
empty database will duplicate each message due to the absence of
local/remote UID association.
