I jumped through many of the same hoops in my last job. There are all kinds of ways you can end up blocked if you're not careful (if you can, make sure the host--read IP--you are using for your outgoing SMTP server is not originating *any* other IP traffic).<br>
<br>I'm surprised you would be blocked for passing through relayed SMTP servers, though. That is very common and a pretty core part of the SMTP system (even gmail relays mail through several SMTP servers). I guess if you were relaying through an IP in a dynamic address database, that could get your spam score bumped up. But you're going to have a hard time getting around that these days.<br>
<br>Although I wonder: can you not configure sendmail on your local machine to forward the mail on without adding itself in a Received header? Then it should appear to your ISP's server just like you are sending it with any other SMTP client directly (hmm... you might have to omit the message ID as well?). I'd be curious if that made any difference.<br>

We used to do that with our Bountiful Baby email. It works fine.
However, it was still flagged as spam for some of our customers,
because their email systems noticed that we relayed from a mail server
(our local sendmail) on through yet another mail server (the ISP's),
and the emails were flagged as suspicious because of that.<br>
<br>
Before doing the above, we used to rely solely on our own SMTP server
and not relay through the ISP, but then some of the email was flagged
as spam I *think* because our SMTP server wasn't a well-known server at
the time (which is why we started relaying through the ISP's server).<br>
<br>
We've never found a completely "fool-proof" solution. Some percentage
of the outgoing emails is always going to be flagged as spam, no matter
what. The trick is to pick the solution that results in the least spam
flags. And it's not easy.<br>
<br>
I've now gone back to just using our own SMTP server, rather than
relaying through the ISP, for emails that are sent directly from our
website, and relaying through the ISP for all the rest. Now that
Bountiful Baby isn't a completely unknown company, I'm thinking that's
going to work out to be the best now. But I'm not sure, and it's still
being tested. And, things seem to always change out from under us, so
what works best today might not work best tomorrow.<br>
<br>
But otherwise I think I would agree with you, and do it the way you
suggest. At least as a starting point.<br><font color="#888888">

I tried that using my own smtp server, but it requires authentication
and doesn't let the e-mail go through. If I try it with a local
sendmail daemon, my guess is that the message is gonna end up in the
spam folder of most people... I remember at university we had this
exercises consisting on sending e-mails through sendmail and straight
via telnet, and they would end up classified as spam, I'm not sure
whether this is the same case tho...<br>
<br>
Does someone have further information on that patch that allows
authentication?<br>
<br>
Thanks!

necessarily, you can connect to any SMTP server. I am not sure if<br>
authentication is built in nowadays, but there was a patch floating<br>
around that would add it.<br>
