No. If you see H.S.' posting you receive by e-mail, it will have
normal unsubscribe trailer.
What H.S.' the posting as he read from gmane has no trailler. This is
correct: all the posting as stored and shown in gmane has no
unsubscribe trailer, regardless on who sent it. I believe the mailing
list manager post it to gmane before trailler attached. This is fine,
since the unsubscribe trailler will not make any sense in a nntp
newsgroup.
I know that he sees no unsubscribe trailer. Our list server may have
special processing to send a copy, sans trailer, to Gmane; I have no
evidence one way or the other on that. Or Gmane could strip the trailer.
Or Gmane could retrieve posts from the archives, and then strip the
trailer. I'm curious about this, but just incidentally.
The issue is that sometimes those of us receiving mail in the normal way
do not see it on some posts we receive from some accounts. I've noticed
this primarily with gmail, and sometimes with AOL, but it is not at all
consistent. I guess I'll have to start collecting some data on this to
see if there's any detectable pattern. Other people have noted this in
the past, as well.
Apparently some Gmane users, like H.S., explicitly subscribe to the list
(but really shouldn't) and get the messages both as email and through
the newsgroup.
* If the emails are sent to your gmail account, Gmane apparently
intercepts and discards them without their being processed by the
gmail server at all, or perhaps gmail has a filter to discard them.
Gmane has no power over that e-mail. I believe H.S. said it in his/her
own footer: that the e-mail will go to a mailbox that never read and
discarded periodically (trash, maybe?).
His (or her -- I'll stick with "his" for convenience) sig implies that
he has made a personal decision about incoming mail to that account,
creating an email client filter that sends it to a mailbox that is
periodically emptied. Other Gmane users may be willing to accept
off-list communications. In any case, this could be about both list mail
and mail not sent from the list, but directly by email to that account.
I was referring purely to list traffic. I was assuming that list mail
was not received on the account, but apparently it is (if the user is
explicitly subscribed to the list). The interesting thing is that there
is apparently no need for the explicit subscription. Posts derived from
the Gmane newsgroup are not routed through the moderators, even if there
is no explicit subscription.
* Gmane apparently has its own subscription to the list and
receives a copy of the emails,
Yes. In a way of speaking.
stripping the unsubscribe trailer and creating a newsgroup post for
you and its other users of this newsgroup.
Not sure about the technicality, but it may use an adapter in the
mailing list manager. So e-mail never actually "sent to gmane", but
the adapter in the mailing list manager automatically posted the
message as part of processing.
* If you decide to stop following the list, you remove it from your
Gmane newsgroup list but do not unsubscribe your gmail account. Does
Gmane unsubscribe you? If not, and the list server is actually
sending messages to you, that would seem to be wasteful of resources.
Right, person who did subscription this way must remember to
unsubscribe his/her e-mail when he stop following the list.
It sounds as if they shouldn't be explicitly subscribed, anyway. If they
are, the copies they get in their email probably have the trailer, and
they should be aware of the need to unsubscribe as well as removing the
newsgroup from their Gmane reader.
