Dear qolleages<g>!
I have just rejoined this very active list to ask a question, and make
a comment. I am running Linux at home, with qmail, and I have an ISP
which I dial up 3-4 times a day(PPP connection) to get my mail(with
fetchmail), or do some browsing if there is a need . . .
My machine's name is alanmcc.net.us, a handcrafted name, totally
unregistered; it might as well be flopsy.mopsy.cottontail. I send
out my mail using user masquerading(FAQ 1.2) so all replies go
to [EMAIL PROTECTED]
My ISP, wizard.net, doesn't do forwarding, so I can't implement any
null-client. And of course I don't have a static IP, I get a new
IP # each time I dial up.
Now a trend is starting to develop of checking, via reverse-lookup,
where E-mail is coming from, before accepting it. I have only hit it
once(when I tried to join the freebsd.org E-list), but it is clearly
an important anti-SPAM measure, and this will increase. I think this
is a good idea, but it makes problems for mail coming from the
machine alanmcc.net.us, or, I guess, any machine connected to the Net
with a dynamic IP.
So I am about to modify my "ip-up" script to do the following: do
an nslookup on the IP # I get sent, in order to get the name of the
"machine" that I've been given, and then insert this machine name into
/var/qmail/control/defaulthost. I have tested this "by hand" e.g.
getting the machine-name and doing a "telnet freebsd.org smtp" with
EHLO etc, and it works.
Finally my question<g>: is this the way to go? or can someone suggest
a less kludgy solution?
More generally: how in general can the average gal/guy(including your
average greedy spammer misfit), get on the Net, and send out whatever
(s)he wants, with the (one?) proviso, that they must -- as the freebsd.org
site makes them do -- identify themselves?
Is it important or relevant to mention here that freebsd.org is using
Postfix? Probably not, since I'm sure that qmail can be configured
to do the same reverselookup, right?
Sorry for the overlong post, hope that someone will have read it to
the end!
TIA for answers!
