I won’t expand on the features in the 6.4 release as I already wrote about the configuration file changes, the issues that required it and the refactors involved, this was the one true major feature of the release. One notable aspect though is that we dropped our support for OpenSSL in favor of LibreSSL, and THAT I should expand upon ;-)
And looking forward...
Filters have been a (the most ?) long awaited feature in OpenSMTPD. I finally committed most of the filters code to OpenBSD.
