Hi Harald,

Thanks for the details!

It is good to hear that this is already supposed to work, but this is not
what I have experienced.  I have set "Host name this list prefers" and it
still returns emails with the main domain name in them.  Maybe I have
something configured incorrectly.  I'll go poke around some more.

What do you mean by "different Mailman-internal names"?  If you meant that
the name of a mailing list can look like one thing to the "world", but can
be a unique name "internal" to Mailman, then I think I understand what you
mean.  See my notes below for more about this.

One thing that I have noticed might be a problem is that multiple domains
might want a mailing list with the same name.  For instance, we have this
mailing list:
	announce at mydomain.com

We've put this into our aliases file to handle it:
announce:                "|/home/mailman/mail/wrapper post announce"
announce-admin:          "|/home/mailman/mail/wrapper mailowner announce"
announce-request:        "|/home/mailman/mail/wrapper mailcmd announce"
owner-announce:          announce-admin
announce-owner:          announce-admin

But, if a customer wanted a mailing list with the same name at their own
domain, I'm not sure what we would do.  I guess we could create a list
called "announce2", and put this in the aliases file:
announce2:                "|/home/mailman/mail/wrapper post announce2"
announce2-admin:          "|/home/mailman/mail/wrapper mailowner announce2"
announce2-request:        "|/home/mailman/mail/wrapper mailcmd announce2"
owner-announce2:          announce2-admin
announce2-owner:          announce2-admin

We would then put this into the virtusertable file:
announce at customerdomain.com         announce2
announce-admin at customerdomain.com   announce2-admin
announce-request at customerdomain.com announce2-request
owner-announce at customerdomain.com   owner-announce2
announce-owner at customerdomain.com   announce2-owner

But the problem is that the emails that get sent from Mailman would still
say "announce2 at customerdomain.com" all throughout them, instead of
"announce at customerdomain.com".

Would your suggested changes solve this problem?

Again, the "Base URL" setting is not working for me.  I'll experiment with
this some more.

We are trying to automate as much of our system as possible.  We would love
to make it so that when a customer orders a mailing list service, it is
automatically installed and configured.  With this in mind, it would really
make sense for the newlist command to be able to accept a bunch of command
line parameters instead of stdin.

Could the newlist command at least include options on the command line for
the list's default URL and for the mail domain?  That way you wouldn't have
to muck up the stdin questions, but people who wanted more control could
have it.  It would be best if all options could be specified on the command
line and any required ones that were not specified would be asked via stdin.

I think that there are many ISPs that would absolutely love a mailing list
system like Mailman if it had virtual hosting support built right in
flawlessly (we certainly would!).  We've managed to tweak Majordomo a bit so
that it kind of works.  And now we've kind of got Mailman working too.  But
we really would like it to make our lives easier in a virtual hosting
environment, since that is pretty much all we do all day long.
