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.

Changes:

- 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.
