interimap - 0.5.6-1 main

InterIMAP performs stateful bi-directional synchronization between two
IMAP4rev1 servers. Compared to the so-called "full" synchronization
solutions, InterIMAP is both much faster and parsimonious in network
traffic.
.
Stateful synchronization is made possible by the QRESYNC extension from
[RFC7162]; for convenience reasons servers must also support LIST-EXTENDED
[RFC5258], LIST-STATUS [RFC5819] and UIDPLUS [RFC4315].
.
Furthermore, while InterIMAP can work with servers lacking support for
LITERAL+ [RFC2088] and MULTIAPPEND [RFC3502], these extensions greatly
improve performance by reducing the number of required round trips and it
thus strongly recommended to use a server supporting these.
.
InterIMAP supports the COMPRESS=DEFLATE extension from [RFC4978]. It is
enabled by default on remote servers advertising it, in order to reduce
network traffic, especially for long-lived connections.
