msmtp 1.8.0rc1 is released

2018-08-20

This is a release candidate for the upcoming 1.8.x stable release series. The following changes were made:

• A minimal SMTP server called msmtpd was added that listens on the local host and pipes mails to msmtp (or another program). It is intended to be used with system services that cannot be configured to call msmtp directly. You can disable it with the configure option --without-msmtpd.
• Using OpenSSL is discouraged and may not be supported in the future. Please use GnuTLS instead. The reasons are explained here.
• As using GNU SASL is most likely unnecessary, it is disabled by default now. Since everything uses TLS nowadays and thus can use PLAIN authentication, you really only need it for GSSAPI.
• The CRAM-MD5 authentication method is marked as obsolete / insecure and will not be chosen automatically anymore.
• If your system requires a library for IDN support, libidn2 is now used instead of the older libidn.
• Builtin default port numbers are now used instead of consulting /etc/services.
• Support for DJGPP and for systems lacking mkstemp() or tmpfile() is removed.
