interimap (0.5.4) upstream;
* libinterimap: make SSL_verify also checks that the certificate
Subject Alternative Name (SAN) or Subject CommonName (CN) matches the
hostname or IP literal specified by the 'host' option. Previously it
was only checking the chain of trust. This bumps the minimum
Net::SSLeay version to 1.83 and OpenSSL version 1.0.2.
* libinterimap: add support for the TLS SNI (Server Name Indication)
extension, controlled by the new 'SSL_hostname' option. The default
value of that option is the value of the 'host' option when it is
hostname, and the empty string (which disables SNI) when it is an IP
+ libinterimap: show the matching pinned SPKI in --debug mode.
+ test suite: always generate new certificates on `make test`. Hence
running `make test` now requires OpenSSL 1.1.1 or later.
+ test suite: sign all test certificates with the same root CA.
+ libinterimap: factor out hostname/IP parsing.
+ document that enclosing 'host' value in square brackets forces its
interpretation as an IP literal (hence skips name resolution).
+ Makefile: new 'release' target; also, change the tag format from
upstream/$VERSION to v$VERSION.
- documentation: replace example.org with example.net for consistency.
- rename 'debian' branch to 'debian/latest' for DEP-14 compliance.

interimap (0.5.3) upstream;
* libinterimap: SSL_fingerprint now supports a space-separate list of
digests to pin, and succeeds if, and only if, the peer certificate
SPKI matches one of the pinned digest values. Specifying multiple
digest values can key useful in key rollover scenarios and/or when
the server supports certificates of different types (for instance
- libinterimap: 'null-stderr' is now ignored when the 'debug' flag is
set (the standard error is never sent to /dev/null).
- test suite: use a RSA certificate rather than ECDSA.
- test suite: new test with a server offering both RSA+ECDSA
certificates. This test requires dovecot-imapd 2.2.31 or later.

interimap (0.5.2) upstream;
- Makefile: remove 'smart' extension from pandoc call to generate
manuals (it's no longer supported by pandoc 2.9 which generates \[lq]
and \[rq] in the groff output anyway).
- libinterimap: fix response injection vulnerability after STARTTLS.
For background see https://gitlab.com/muttmua/mutt/-/issues/248 .
- libinterimap: abort on PREAUTH greeting received on plaintext
connections (set "STARTTLS = NO" to ignore). This is similar to
CVE-2020-12398 and CVE-2020-14093.
* libinterimap: fail when a capability to ENABLE is missing from the
server's CAPABILITY listing.
-- Guilhem Moulin <firstname.lastname@example.org> Mon, 03 Aug 2020 20:50:41 +0200
interimap (0.5.1) upstream;
+ pullimap: also compare RFC 5322 date and envelope information in
mailbox comparison tests.
+ interimap, pullimap: remove `use lib` statement.
* Makefile: major refactoring, add install and uninstall targets, honor
BUILD_DOCDIR and DESTDIR variables.

interimap (0.5) upstream;
* interimap: when matching mailbox names against the 'ignore-mailbox'
pattern, the hierarchy delimiter is substituted with a null character
before hand. For instance one should now use '^virtual(?:\x00|$)' to
exclude the mailbox named 'virtual' as well as its descendants
(regardless of the hierarchy delimiter in use).
* interimap: the space-speparated list of names and/or patterns in
'list-mailbox' can now contain C-style escape sequences (backslash
and hexadecimal escape).
* interimap: fail when two non-INBOX LIST replies return different
separators. This never happens for a single LIST command, but may
happen if mailboxes from different namespaces are being listed. The
workaround here is to run a new interimap instance for each
* libinterimap: in tunnel mode, use a socketpair rather than two pipes
for IPC between the interimap and the IMAP server. Also, use
SOCK_CLOEXEC to save an fcntl() call when setting the close-on-exec
flag on the socket.
* interimap: new option 'list-reference' to specify a reference name.
This is useful for synchronizing multiple remote servers against
different namespaces belonging to the same local IMAP server (using a
different InterIMAP instance for each local namespace <-> remote
synchronization, for instance with the newly provided systemd
template unit file).
* Add a test-suite. (Requires dovecot-imapd, pkill(1) and xxd(1).)
* Completely refactor the documentation. In particular, move manpages
to a new 'doc' directory, and generate HTML documentation with `make
+ interimap: write which --target to use in --delete command
+ interimap: avoid caching hierarchy delimiters forever in the
database. Instead, use null characters internally, and substitute
them with the local and remote hierarchy delimiters (which thus no
longer need to match) for IMAP commands. This require a database
schema upgrade to alter the mailbox name column type from TEXT to
+ interimap: use the 'user_version' SQLite PRAGMA for database schema
+ interimap, pullimap: in the manpage, clarify that the tunnel command
is run following Perl's `exec` semantics: it is passed to `/bin/sh -c`
when it contains shell metacharacters; and split into words and passed
to execvp(3) otherwise.
+ interimap, pullimap: redact AUTHENTICATE and LOGIN commands in
--debug mode in order to avoid inadvertently receiving credentials in
bug reports. --debug can be set twice to spell out these commands in
+ interimap: new option 'log-prefix' to control the prefix of each log
entry, depending on the component name and relevant mailbox.
+ interimap: raise SELECT sample range size from 64 to 256 bytes.
- libinterimap: bugfix: hierarchy delimiters in LIST responses were
returned as an escaped quoted special, like "\\", not as a single
character (backslash in this case).
- libinterimap: the parser choked on responses with non-quoted/literal
astring containing ']' characters. And LIST responses with
non-quoted/literal list-mailbox names containing '%', '*' or ']'
- libinterimap: quote() the empty string as "" instead of a 0-length
literal. (This saves 3 bytes + one round-trip on servers not
supporting non-synchronizing literals, and 4 bytes otherwise.)
- interimap: unlike what the documentation said, spaces where not
allowed in the 'list-select-opts' configuration option, so at maximum
one selector could be used for the initial LIST command.
- interimap: unlike what the documentation said, 'ignore-mailbox' was
not ignored when names were specified as command line arguments.
- interimap: accept comma-separated values for --target.
- interimap: --rename of a \NonExistent mailbox didn't trigger a RENAME
command on the local/remote IMAP servers, nor an update of the
- interimap: don't try to delete \NoSelect mailboxes (it's an error per
RFC 3501 sec. 6.3.4).
- interimap: SQLite were not enforcing foreign key constraints (setting
the 'foreign_keys' PRAGMA during a transaction is a documented no-op).
- interimap: fix handling of mod-sequence values greater or equal than
2 << 63.
- libinterimap: use directories relative to $HOME for the XDG
environment variables default values. Previously getpwuid() was
called to determine the user's home directory, while the XDG
specification explicitely mentions $HOME. Conveniently our docs
always mentioned ~/, which on POSIX-compliant systems expands to the
value of the variable HOME. (Cf. Shell and Utilities volume of
POSIX.1-2017, sec. 2.6.1.)
- libinterimap: don't panic() when inflate() reports the end of the
compression stream is reached.
- libinterimap: the 'compress' boolean wasn't honored.
- libinterimap: fix STARTTLS directive, broken since 0.2.
- libinterimap: push_flag_updates(): the UNCHANGEDSINCE test from
the CONDSTORE extension was incorrectly placed after the flag list in
UID STORE commands.
- libinterimap: push_flag_updates(): ignore UIDs for which no untagged
FETCH response was received.
- libinterimap: push_flag_updates(): don't ignores received updates (by
another client) to a superset of the desigred flag list.
- libinterimap: avoid sending large UID EXPUNGE|FETCH|STORE commands as
they might exceed the server's max acceptable command size; these
commands are now split into multiple (sequential) commands when their
set representation exceeds 4096 bytes in size. Performance could be
improved by pipelining but given the scope of this software
(synchronization) it's unlikely to make any difference in practice.
This is a also a workaround for a bug in Dovecot 2.3.4:
- interimap: for the reason explained above, limit number of messages
to 128 per APPEND command (only on servers advertizing MULTIAPPEND,
for other servers the number remains 1).
- interimap: gracefully ignore messages with a NIL RFC822 attribute.
- pullimap: treat messages with a NIL RFC822 attribute as empty.
- pullimap: fix mangling of data lines starting with a dot (when an RFC
5322 line starts with a '.', double it).

interimap (0.4) upstream;
* pullimap: replace non RFC 5321-compliant envelope sender addresses
(received by the IMAP FETCH ENVELOPE command) with the null address
* pullimap, interimap: take configuration filename (default: "config")
relative to $XDG_CONFIG_HOME/$NAME (or ~/.config/$NAME), to comply
with the XDG specification. Thus the previous default config file
$XDG_CONFIG_HOME/$NAME should become $XDG_CONFIG_HOME/$NAME/config.
* Library: add support for TLSv1.3 (on recent enough Net::SSLeay), and
change "SSL_protocols" default value from "!SSLv2 !SSLv3" to "!SSLv2
!SSLv3 !TLSv1 !TLSv1.1".
+ Library: new API idle_start() and idle_stop().
+ Add support for untagged ESEARCH responses from RFC 4731.
+ pullimap: Use extended SEARCH commands (RFC 4731) if supported by
the server to search old mail and EXPUNGE them.
+ pullimap, interimap: don't autocreate statefile or database in
long-lived mode (when --watch or --idle is set). Instead, an error
is raised if the statefile or database doesn't exist.
- Ensure the lower bound of UID ranges is at least 1.
- Fix manpage generation with pandoc >=2.1.
- Specify minimum Perl and Net::SSLeay versions.
- interimap.service: use --watch=60 rather than --notify, because
dovecot's NOTIFY extension doesn't seem to work so well as of 2.2.27.

deliver them to an SMTP session.
+ Convert manpage format from groff to pandoc.
