* imap.c, isync.h, maildir.c, sync.c:
|
||||||
|
RFC822.PEEK is obsolete in RFC2060. Use BODY.PEEK[] instead, which does
|
||||||
|
the same thing
|
||||||
|
|
||||||
|
keep track of the uidvalidity so isync can detect if the mailbox on the
|
||||||
|
server has changed since the last sync.
|
||||||
|
|
||||||
|
* NEWS: updated NEWS for 0.3 release
|
||||||
|
|
||||||
|
* Makefile.am, isync.spec:
|
||||||
|
added support for building RPMS
|
||||||
|
|
||||||
|
* Makefile.am, isync.1:
|
||||||
|
added target for creating html version of the man page
|
||||||
|
|
||||||
|
documented the imaps: prefix to the Host command
|
||||||
|
|
||||||
|
* imap.c, sync.c:
|
||||||
|
can't assume flag order when fetching a message. just search for the
|
||||||
|
first `{' to find the message size.
|
||||||
|
|
||||||
|
* isync.1, sync.c:
|
||||||
|
added BUGS section to manpage detailing the fact that we break the
|
||||||
|
maildir(5) spec by parsing the filename
|
||||||
|
|
||||||
|
change message delivery to use the method described in maildir(5)
|
||||||
|
|
||||||
|
* configure.in, main.c, sync.c:
|
||||||
|
use getpass() to get the user's password
|
||||||
|
|
||||||
|
unlink the temp file if we are unable to fetch a new message from the
|
||||||
|
server.
|
||||||
|
|
||||||
|
update version to 0.3
|
||||||
|
|
||||||
|
* isync.1: fixed typo in man page for --verbose option
|
||||||
|
|
||||||
|
* Makefile.am, README, TODO, imap.c, isync.h, list.c:
|
||||||
|
added generic IMAP list parser and rewrote imap_exec() to handle
|
||||||
|
arbitrary data instead of hardcoded
|
||||||
|
|
||||||
|
* Makefile.am, README, configure.in, main.c:
|
||||||

fixes to compile cleanly under Solaris 2.7
|
||||||

* ChangeLog, configure.in, main.c:
|
||||||
|
config options were not case insensitive
|

[0.4]
|
||||||
|
|
||||||
|
Added MaxSize configuration option to limit downloading of new messages from
|
||||||
|
the server to less than some threshold.
|
||||||
|
|
||||||
|
More robust --fast option works without using \Recent flags, so the previous
|
||||||
|
problem with multiple accesses killing these flags is no longer a problem.
|
||||||
|
|
||||||
|
RFC2060 obsoleted RFC822.PEEK, use BODY.PEEK[] instead which does the same
|
||||||
|
job.
|
||||||
|
|
||||||
|
Don't need to request UID in a FETCH when doing UID FETCH (RFC2060 states
|
||||||
|
that its automatically returned).
