No bug here. "mailto" is the URI for email addresses (just as "http"
is for urls). The problem was your including that as part of the
address you were sending to. From the information provided, the
correct address is (simply):

[e-mail]

Email clients and web browsers understand the "mailto" URI and handle
things automatically. When doing a copy/paste you simply need to
strip the mail URI.

Fascinating mailing list bug

Allegedly, on or about 02 July 2016, Richard sent:

Perhaps not a bug, but certainly peculiar.  None of the other email
headers that have email addresses in them include a mailto: prefix (to,
from, reply-to, in-reply-to, envelope-to, return-path, x-mail-from,
numerous received-from headers), only the list-mail identifying
additions to the headers.  Yet it doesn't appear in the message
boilerplate showing in the footer (at the bottom of this message, once
it goes through the list server, you'll find: users mailing list
[e-mail] added to the bottom, sans mailto:).

You could argue that it *ought* to be present in all of the mail headers
(though it's mostly redundant, since there's a header name before the
data - to, from, etc.), though it could be useful to something else as
the prefix for the message-id, that stops it being misidentified as an
email address.

The mailto: prefix is something I'm used to seeing in HTML webpages,
where *you* are going to click on a rendered link, rather than playing
copy and paste with the source.  So, thankfully, I'd know to delete it
when finding it before an address.  I'm not so sure about others,
particularly the casual user who subscribed to fix a fault, then cannot
figure out how to un-subscribe, and eventually mails the list asking how
to stop being spammed (their words).

Thunderbird did it. Control-U to see the raw message. Clipped address out of the 
raw header material. Must have included the "mailto:" in the clip. (It would be 
sensible of T'bird to correct such an error but that's another world, entirely.)

The really interesting thing is that I resent the message to the correct address 
as clipped from the header of one of the well over 100 messages today. I got 
back a reply that I'm not a member of the list. Something is highly schizoid 
there. Hm, MAYBE I figured it out. I may have subscribed with my junkmail 
address. Checking.... Send from the junk address - wait for return - Ah so - my 
bad. I had forgotten I'd used the junkmail address a LONG time ago.

So it's all a non-issue. Sorry to bother people.

{o.o}	Shame on me.
