[Lynx-dev] (a) list mail format error; (b) broken owner- address


From: Mouse
Subject: [Lynx-dev] (a) list mail format error; (b) broken owner- address
Date: Thu, 12 Aug 2021 13:48:12 -0400 (EDT)

My apologies to most listmembers for the noise; the usual address to
reach the listowner doesn't seem to be working (see below).

I tried to send mail to lynx-dev's owner- address, raising a
consistent malformatting issue in list mail (see below), and got a
bounce indicating even more issues.  So I'm wondering if I could get
whoever runs the list to (a) deal with the issue I tried to raise and
(b) fix (or at least get fixed) the issue that prevented the mail from
getting through?

For (a), here's the content I tried to send:

----------------
I've been noticing, for a while now, that lynx-dev list mail has been
coming in with a minor format violation.

Specifically, it shows up as (to quote a recent list mail)

Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64

but, while the base64 encoding is valid, the decoded content is not
valid text/plain; it represents line breaks as bare 0x0a octets,
without any preceding 0x0d octets.  (See RFC2046 4.1.1.)

I would, of course, recommend you fix or replace whatever is
responsible for this malformatting.
----------------

For (b), the bounce I got says

The problem with this is twofold: first, there's the problem with the
whole paradigm, in that it farms out part of spam filtering to entities
with no particular incentive to do it the way eggs.gnu.org wants it
done; second, there's the implementation problem, in that the verify
code doesn't seem to know how to speak SMTP.  It dropped the connection
slightly over 60 seconds into my banner delay, a point at which any
client-side timeout SHOULD be at least five minutes (RFC2821 4.5.3.2):
