Naming of network/domain and outgoing mail
#433

I have registered a domain name through www.gradwell.com, and paid for
web/email forwarding. So it seems appropriate to rename my network to
match. I forsee some difficulties with mail transport and would
appreciate some pointers before I go and mess it up!

My domain is w-c-f.org.uk, so probably I shall name my linux box as
w-c-f.org.uk and others on my lan as subdomains e.g. simon.w-c-f.org.uk
(Or maybe the linux box should be somename.w-c-f.org.uk - I've just
checked and found that http://w-c-f.org.uk takes me to my website, so
naming my box as w-c-f.org.uk is perhaps not such a good idea!)

1) Sometimes I shall want to send mail to someone@w-c-f.org.uk (which is
directly forwarded by gradwell to fred@another.isp) and want it to get
out of here. I suspect that sendmail (8.9.1) will not be inclined to
send it out since it will regard anyone@w-c-f.org.uk as local? Do I have
to do anything special here? (This will apply to a maximum of five
names, so some simple workaround will suffice - maybe an alias to
someone%w-c-f.org.uk@smarthost ?)

2) Similarly what about majordomo? Currently majordomo runs as
majordomo@child.demon.co.uk with maillist-L@child.demon.co.uk  OK, I'll
have to tell the list members the new address. Presumably if I name the
linux box as w-c-f.org.uk then majordomo will name the lists as
maillist-L@w-c-f.org.uk etc or maillist-L@somename.w-c-f.org.uk if I
call it somename.w-c-f.org.uk? Is that all there is to it, majordomo
will pick up whatever name I give the linux box? I think so, and perhaps
this emphasises the importance of getting the lan renaming correct first
go, since I shall want the mailing lists to end up with sensible and
stable names.

Any comments welcomed

You don't have to accept email for that domain as local (listed in
sendmail.cw or class W).  I have much the same setup for
netscum.org.uk and the people who do your email redirect actually
rewrite the smtp envelope to whatever domain you specified.  So as
long as sendmail accepts whatever email address you've had it
rewritten to you'll be fine.

Majordomo will dealt with whatever lists it's given to my knowledge
(when you set up the alias remember you tell it what email address
it's serving).  It will deal with list@box.demon.co.uk and
list@box.co.uk in the same way if someone rewrites the smtp envelope
box.co.uk to box.demon.co.uk.

Ah, good point. That solves that one.

Prompted by James' posting I've just found the wherami in majordomo.cf.
I did of course have a look before posting but it's so long since I set
it up I was looking in the wrong place (I was looking in the individual
lists config and had forgotten about majordomo.cf).

As you imply, and which I was overlooking, since the incoming mail has
had it's incoming address rewritten, majordomo will not even see it as
w-c-f.org.uk, so in a sense nothing changes except for the info in
majordomo.cf

Thanks

Hmm, good point. This is the sort of reason for my asking before I
leap...

Of course I would have preferred wcf.org.uk but it had already gone :-(

The latter, so in fact I'm not receiving mail as w-c-f.org.uk anyway...

..so this doesn't apply

Probably just using the hosts file would be enough, wouldn't it?

I had forgotten about majordomo.cf, which seems to solve all this.

Yes I had thought of that

.. to get it wrong ;-)

Thanks to both of you, I'm clearer now:

I think there's no real need to rename. It would be a little tidier,
e.g. Outlook Express, as well as stripping the trailing space off my sig
separator :-(( gives email message id's of xyz@tower.localdomain instead
of 123@simon.w-c-f.org.uk, but it's only a nicety

Incoming and outgoing mail should work alright (indeed are doing already
as I haven't done any renaming)

A tinker with majodomo.cf and the associated aliases should sort out the
lists.

Might cause me dns work if I rename.

Cheers
