New development build of Courier is available. The major change is a top-to- bottom rewrite of the SMTP client, and a new mail filter (making use of the rewritten SMTP client). The SMTP client rewrite will result in a (several) version change bump, down the road.

The OpenSSL 1.1.0 change is also in the courier-imap package, and the maildrop change in the maildrop package.


- OpenSSL 1.1.0 update. Custom protocol level format selection has been deprecated. The TLS_PROTOCOL setting is removed from all configuration files, and the latest supported TLS version will always be used. No changes to the GnuTLS alternative option.

- maildrop: added the new "system" command.

- The SMTP sending code has been rewritten and factored out into an internal library.

- New "verifyfilter" module, a filter module that verifies the email sender address by initiating a callback connection to the sender's domain, using the internal SMTP library. The module is also available as a "verifysmtp" command-line tool, that does the same.
