cygport announce fails unable to find mailserver

[Brian Inglis]

Hi folks,

Do any/some/many of you use cygport ...cygport announce to generate your update
announcements, and does it work successfully?

It has never worked for me, but Thunderbird, git send-email, mailx, mail, email,
s-nail, my own scripts, with similar configs, and telnet, work okay, as shown at
the bottom of this email and the log.

Any ideas why cygport ... announce using perl libnet/Net::SMTP would have
problems, how to diagnose or debug, and fix?

Relevant code follows +/_pkg_announce /usr/share/cygport/lib/pkg_upload.cygpart

Attached log has irrelevant output and escape sequences removed, commands added,
and remainder sanitized; summary is:

$ cygport --debug tzcode.cygport announce |& tee cygport-announce-no-mailserver.log

The following packages have been uploaded to the Cygwin distribution:

* tzcode-2020d-1

The Time Zone Database (often called tz, tzdb, or zoneinfo) contains
data that represents the history of local time for many locations around
the world, and supports conversion of UTC time to local time at those
locations to allow display of those local times. It is updated
periodically to reflect changes made by political bodies to daylight
saving (summer time) rules, UTC offsets, and time zone boundaries.
This package provides the tzselect, zic, zdump utilities.
