The OpenSMTPD portable version from
works fine on Slackware64 current with OpenSSL 1.1.1c and gcc 9.2

It took me a while to get it to work though.

I first downloaded the "current" portable version from

And I got errors very similar to those of Denis Fateyev on Fedora 30.

Next I downloaded the portable version from
and found that autoconf had not been run and this was no good.

Finally I discovered the post on the mailing list which mentioned the
"bootstrap" script and then I was able to download and build the portable
version from git.

The code shows version "6.6.0-portable".

It runs fine on Slackware64 current and I'm happy that it now works with
OpenSSL 1.1
