After hours of testing, nailed down cygport ... announce SMTP issues.

ISP requires non-default Net::SMTP Hello parameter - localhost.localdomain is
rejected - and does not allow or recognize first initial header "From " line!

So we need to drop the first initial header "From " line, and pass the Hello
parameter with a non-default mail domain value.
Suitable mail domain values available are provided by the Net::Domain
hostdomain, hostfqdn, domainname functions, or the From address domain:
the attached patch uses the first and overrides with the last if available.
