[Fetchmail-announce] ANNOUNCE: The 6.5.7.rc2 release candiate of fetchmail is available (SMTP AUTH fixes & .netrc support - NO (START)TLS yet)

[Matthias A. <mat...@gm...>]

The 6.5.7.rc2 release candidate of fetchmail is now available at the 
usual locations, including
<https://downloads.sourceforge.net/project/fetchmail/branch_6.5/>.


Changes are listed below, but I have added wolfSSL and GSSAPI support to
meson-based builds.  I'd be happy to receive reports from people building with
meson if that works for you or if not, where not, how not.

I have not added all the tiny disable options to meson we used to have in
configure.ac, the POP3/IMAP features take 10...12 kByte on AMD64, and the
ETRN/ODMR less than 3 kByte each, in a 280 kByte sized executable.


The source archive is available at:
<https://downloads.sourceforge.net/project/fetchmail/branch_6.5/fetchmail-6.5.7.rc2.tar.xz/download>

The detached GnuPG signature is available at:
<https://downloads.sourceforge.net/project/fetchmail/branch_6.5/fetchmail-6.5.7.rc2.tar.xz.asc/download>

The SHA256 hashes for the tarballs are:
SHA2-256(fetchmail-6.5.7.rc2.tar.xz)= 6b0a5aa50316b894b493c69e9c7c9ad5d8047df4703f483e97ed0a22a509172d

Note I have moved the tag after pushing it for the first time; it was on 686b6 first where I hadn't
committed the NEWS, configure.ac and meson.build file's bump to rc2 and crediting Besnik for the Shqip
(Albanian) translation, but the tarballs had already been built with the contents of what's now fd34e417.

Here are the release notes:
--------------------------------------------------------------------------------
fetchmail-6.5.7 (not yet released):

## BUGFIX:
* When authenticating to an SMTP server, the AUTH LOGIN method (which didn't
  become a proposed standard, and is only the third method fetchmail would try,
  if CRAM-MD5 and PLAIN weren't offered) required that the server returned
  a 334 code followed by a blank and by a decodable base64 challenge we ignored
  anyways.  This is in line with RFC 4952.
    However, to improve compatibility, fetchmail now accepts anything that
  starts with "334 " and disregards the remainder of the line.
  At the same time, AUTH LOGIN was deprecated. AUTH PLAIN should be available
  everywhere AUTH LOGIN is, and is specified in IETF RFC 4616.
* When authenticating to an SMTP server, i. e. esmtpname/esmtppassword are
  defined, check for errors, and skip servers that do not understand EHLO,
  because we cannot negotiate supported authentication schemes with them.
  This should avoid attempting to send a lot of messages and see them rejected.
* When authenticating to an SMTP server, do not send client abort "*" when
  we receive any other server reply but 334.
* Extend 6.5.6's RFC-5321 address-literal fix to MAIL FROM. This might
  apply when we only have a server's IP address and need to quality
  addresses without domain. Fixes Debian Bug#1080025.
* SMTP AUTH can now look up passwords from the .netrc file - for that,
  fetchmail's esmtpname setting must match the login for the given host in
  .netrc. Fixes Debian Bug#1056651 by Ticker Berkin.
