The really big question here is the relationship between our
/etc/services and

  https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt

The format you don't like seems to be sort of similar to the one from
IANA.  But we are quite out of sync from that, so I wonder about the
other BSDs.

Looking at the CVS history of src/etc/services (you didn't mention this,
but it is of course highly informative):

So I would talk to them and see what they did and why; it seems like
there must be a script from an iana file, and then there's supposed to
be the "local additions" section.  Probably the real bug is losing that
and it can be put back.  But editing without understanding that flow
seems unwise.

Files generated like this usually have a Big Scary Warning, and this
doesn't; probably someone(tm) should fix that.

On the substance:

The use of mail for port 465 was apparently assigned briefly and then
not (we have STARTTLS now), and how is assigned to urd.  I never thought
it was for submission.  It is not in the current IANA file.  So it's a
good question why it remains at all.  I am therefore not ok with adding smtps.

I wonder why kamanda is commented out.  Probably because it conflicts
and it is not assigned by IANA.

I think the issue is the semi-automated nature and not everybody being
clear on that.

For now, I would say not ok about smtps -- I think we need to understand
the larger plan of tracking upstream and if we are off plan how that
happened.

Let's hear from the people that have been maintaining this.
