pullimap - 0.5.7-4 main

PullIMAP retrieves messages from an IMAP mailbox and deliver them to an
SMTP or LMTP transmission channel. Compared to alternatives such as fetchmail
or getmail, PullIMAP trades flexibility and IMAPd compatibility for
performance.
.
A statefile is used to keep track of the mailbox's UIDVALIDITY and UIDNEXT
values. While PullIMAP is running, the statefile is also used to keep
track of UIDs being delivered, which avoids duplicate deliveries in case the
process is interrupted.
.
PullIMAP supports the COMPRESS=DEFLATE extension from [RFC4978]. It is
enabled by default on servers advertising it in order to reduce network
traffic, especially for long-lived connections (when IDLE commands are
enabled.)
.
An optional retention period can be set to automatically remove old messages
from the IMAP server.
