sysutils/geomWatch outage due to mail/libesmtp show_bug.cgi?id=229017

[Harry Schmalzbauer]

Hello,

one not so prominent openssl111 victim is mail/libesmtp, already reported in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229017

This prevents sysutils/geomWatch to run on FreeBSD 12.

Unfortunately I can't  provide an aedequate patch.
Anybody else who already ironed out openssl compat nits?

Thanks,

-harry
