I thought that each IP should have exactly one A record. I want that
one to be www.my-org.org. Currently, I have a CNAME record for
list.my-org.org. But...

If somebody looks the machine up by IP, I'd like them to see www.my-org.org,
not list.my-org.org. But I'd prefer not to have www show up in the
headers. I thought I might accomplish this by assigning another IP to
the same machine and giving *that* IP the A record for list.my-org.org.

I don't seem to need this if the record is a CNAME, but I can see where
I would if it were an MX or A record.

That works, except for the headers of outgoing messages, which are generated
by sendmail (see example below). (The listserv is Mailman, FYI.) So can I
get sendmail to rewrite the headers for listserv mail to be list.my-org.org?
Thanks.
