This is to announce the release of GNU mailutils version 3.7.

GNU mailutils is a protocol-independent framework for email processing.
It provides a set of libraries for doing almost any mail-related task on
any existing mailbox format, using a consistent format-independent API.

Several tools are built atop of these libraries and included in the package.
Among them are pop3 and imap4 servers, the traditional mailx mail reader,
the sieve mail filtering utility and a complete set of MH utilities
compatible with GNU Emacs MH-E mode.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify mailutils-3.7.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver --recv-keys 3602B07F55D0C732

and rerun the 'gpg --verify' command.

Noteworthy changes in this release:

* Support for the new mailbox format - dotmail

Dotmail is a replacement for traditional mbox format, proposed by
Kurt Hackenberg. A dotmail mailbox is a single disk file, where
messages are stored sequentially. Each message ends with a single
dot (similar to the format used in the SMTP DATA command). Any dot
appearing at the start of the line is doubled, to prevent it from
being interpreted as end of message marker.

* Improve automatic mailbox format detection

This release introduces a notion of accuracy level for the purpose of
mailbox format detection.

Selecting the accuracy level allows the user to achieve the desired
balance between the speed of the folder scan and accuracy of mailbox
format detection.

The accuracy level can be set either from the configuration file,
using the mailbox.accuracy-level statement, or from the environment,
via the MU_AUTODETECT_ACCURACY variable.

The default accuracy level 1 discerns valid mbox and dotmail mailboxes
providing reasonable scan speed.

Level 0 (previous default) does not discern them, but provides maximal

Level 2 and higher provide better accuracy at the price of speed.

* Bugfixes

** mh - correctly parse +/abs/path folder specification
** tls - fix handle interruptions in read routine
** URL parser: use case-insensitive comparison for auth and host parts
** maidag: fix coredump in daemon mode
** movemail: make sure UIDLs are properly stored.
** mail: force mime mode if at least one attachment was given
