Earthlink does NOT require pop-before-relay when you use their
mail-server from inside their network (in other words when you're dialed
in through Earthlink).  Earthlink does NOT let you use any other
mail-server.

You do this only one time when you set up Eudora.  If you dial in
through Earthlink and log in through Earthlink, then all your
personalities need Earthlink's smtp server set up as the Eudora outgoing
mail server.

Believe me you don't have to drop Earthlink accounts.  I don't know why
you're not following what I'm writing, but I can set it up for you on a
system of yours, or write step-by-step instructions for you, if you'd
like (we do charge for custom services).

I've used Earthlink dialup myself, from Northern Idaho, during several
trips within the last year, and NEVER had a problem; I just set the
laptop's copy of Eudora to use pop.nobaloney.net as my pop server and
smtp.earthlink.net as my smtp server.  Works seamlessly.

Look at your own headers:
---
Received: from psi-hq2.garden.net (unverified [216.182.20.98]) by
gate.tellurian.net (Rockliffe SMTPRA 4.5.6) with ESMTP id
<B0037769523@xxxxxxxxxxxxxxxxxx> for
<cobalt-developers@xxxxxxxxxxxxxxx>; Mon, 17 Dec 2001 14:22:17 -0500
Message-ID: <5.0.0.25.2.20011217141015.034eb370@xxxxxxxxxxxxxxx>
X-Sender: jale@xxxxxxxxxxxxxxx
X-Mailer: QUALCOMM Windows Eudora Version 5.0
To: cobalt-developers@xxxxxxxxxxxxxxx

Your headers show that you're jale@xxxxxxxxxx sending email from a
machine called mail.garden.net, using an smtp server called
gate.tellurian.net running Rockliffe's SMTP mailserver, version 4.5.6.

So what???

Do your clients want all the headers in their outgoing email to show
their own domain name?  The only way that's going to happen, EVER, if
they use their own dedicated server.

For example, I just sent myself a test email from my own email
address@xxxxxxxxxxx; it's a small ISP I used to own and I still do
contract services for them.  I used smtp.socalix.com as the server, but
you see the server shows up as smtp.popsite.net, which is the reverse
DNS name of the mail server.

Here's what the headers look like:
---
Received: from smtp.popsite.net (smtp.popsite.net [216.126.128.17]) by
ns1.ns-one.net (8.10.2/8.10.2) with ESMTP id fBJIXTT07340 for
<jblists@xxxxxxxxxxxxx>; Wed, 19 Dec 2001 10:33:29 -0800
Received: from jc300.socalix.com (c3T2-085.015.popsite.net
[216.126.186.85]) by smtp.popsite.net (Postfix) with ESMTP id C0A554C314
for <jblists@xxxxxxxxxxxxx>; Wed, 19 Dec 2001 12:32:05 -0600 (CST)

Every mail-server on the Internet works this way.  You can rewrite
headers on your server so the first received line (actually the bottom
one, as they're added at the top) would show whatever you want, but you
can't change the second one (the top on in the example below), it'll
always show the reverse DNS name of the smtp server used.

So if your client doesn't want to see anyone else's smtp server in the
headers, they need their own system.

(And just to avoid future questions, if you have more than one reverse
DNS records for the IP# with one for each domain, it still doesn't mean
the right domain name will show up; it only means that one will show up
as random from the set of reverse records you've created.)

No way around this.  No matter what company they use.
