The procedure of: fill in the joining form, reply to a confirmation
email is a standard step in most mailing lists these days. It serves two
purposes: it catches misspelt email addresses (because the confirmation
email fails) and it rejects most spam robots (because they don't process
the confirmation email, and generally don't provide anything but lies in
email address fields anyway).
If there were no spammers and no misconfigured user mail clients and no
misfilled forms then this step would not be necessary. But it is because
is so greatly reduces trouble.

Regrettably, "bounce" has a specific meaning in the email context: it is
email that could not be delivered, and that generates a reply message to
that effect from the mail systems involved. The automatic reply message
is called the "bounce".
So your unfortunate (though undertandable) choice of word because
confusing in the context. I find that when I have this situation (for
me, posting in a forum/list where I'm not up to speed with the
terminology since I have no non-English ability sufficient for
conversation) I will use a whole phrase or even a whole sentence to
provide more context for what I mean.
For example, here you could have said "In order to do that I have to
subscribe, and spent some timing bouncing from one task to another to do
so, and that's the problem." That's normal English usage of the term.
"bounces" is a noun and implies a more concrete meaning. The downside is
the difficulty of know which particular terms you are using may have a
specific meaning in the discussion domain.

This is the standard answer of the spammers too. It is the difference
between "opt-in" and "opt-out" junk mail. Advertisers always argue that
they should be free to put people on their mailing lists and that people
should opt-out when they get the junk. This places the burden on every
individual receiver of the mail, and is unreasonable.
So too with requiring end users to need arbitrary filtering technology
at their end; they should not need to make the effort and in many cases
a sufficient effort is not feasible for them (varying mail tools,
varying expertise, varying interfaces). Imagine the poor user of a
web mail interface - they can't attach arbitrary filters at all. Shall
they change their entire mode of interaction to deal with the fallout
from _your_ desire that they should receive (at the pre-filter stage)
all the junk in the world?

| Really? So I don't subscribe I'm a looser whose posts are not welcome?
Well, if you don't subscribe you're too lazy to meet the very low bar to
entry to the discussion; maybe you're not desirable. This isn't so in
your case, since you're clearing prepared to argue cogently for your
point of view. But for the many many spammers it _is_ the case that they
are not welcome.
| And if some random guy manages to subscribe (which according to a
| previous post it's easy), then it's post is worthwhile?
It means they've made an effort: they are probably not a spammer and
probably not a robot and _are_ probably more motivated to participate in
a valuable way. So yes, _probably_ they are more worthwhile.
| I don't think so. Also, how do other big guy mailing lists manage
| without enforcing subscription? Looser posts are ignored... easy.
Really? I've run my share of lists. I will _never_ willingly run a list that
doesn't require people to subscribe to participate .

| Exactly. That's what spam filters are for.
They need to run at the end user, and the end users are varied.
And the burden is unreasonable.
If you argue that the filters should run at the list end, well the
subscribe-to-post rule _is_ a spam filter. And you're objecting to it.

| No, it takes time, but eventually it gets posted. I do this on many lists.
Not on all lists. Moderators often lack the time. I speak as one such,
and some posts simply don't make it because they have waited too long
for attention. It is not scalable. If the list is very active, the
problem gets far worse.

Shrug. For mail clients that distinct is usually irrelevant.

Plenty of people don't want a personal CC; they want all replies on the

It might help if you said what you think _is_ the smart thing. Since

justification is needed _after_ you describe "the smart thing".

Bah. Nothing need to use it.

Demonstrably false. I file my email in _exactly_ the same way, and it
works just fine.
I _suspect_ you mean that you want the post sent to you directly in
addition to the list (though you have not said it). Presumably so you
can track the discussion more easily, and that is a rasonable desire
(the tracking ability, not the particular implementation).
There are other ways.
For example, I colour threads in which I have participated distinctively; I
can then see them easily when browsing my "unix lists" mail folder.
Also, I _always_ press group-reply/reply-to-all and never plain reply,
and then I consider the resulting to/cc headers and edit if suitable.
That bypasses your reply-to issue altogether.
| > Because that's where the post was

| Only because of Relpy-To munging; it's a vicious circle.
And yet often desirable.
Plenty of people are incapable of keep the discussion on list (with
or without cc-to-author). Yea, even my mother in personal email often
drops the CC to my partner. The reply-to makes that work for this list.

| You are speculating, and doing it wrong.
He's not speculating, it is empirically true. The degree to which it is
true varies, but the effect is real and not small.

You can't tell how much escapes, because you do not see the escapes.
So it may well largely work, but it is unreliable.

Demonstrably false. My MUA has those choices. And I use the second one and
edit where it turns out to be not desirable (infrequent).

| Reply-To overrides the Cc too.
_If_ you use the mailer's "conventional reply" operation. And even then,
the outcome is more right than not.

It is such an argument. You may not weigh it heavily, but we do.

Funny, you're not keeping your prejudices to yourelf.
Look, the list setup is the list _policy_. And _this_ list's policy it
to require subscription to keep out spammers and to hack the reply-to to
keep discussions on list. These two things are very effective for the
purposes desired here.
If you don't like it, make your own list and see how it fares. You are
not forced to use this list. And you are _not_ forced to honour the
reply-to setting either.
On the same reasoning you use earlier, that end users should have to
implement spam filtering themselves, I feel that _you_ should be _happy_
to implement "work around the reploy-to" yourself in your MUA.

Well, your "users should do their own spam filtering" uses that logi.

A job for their MUA. It's perfectly doable. Go and do it.
