Hi All: I colo a 2003 Web Edition webserver for a client which has a static
IP and single domain on it. They send mail from the website using CDOSYS and
the SMTP Service. THere's a valid PTR record for the webserver's IP. The
domain has an MX record which has nothing to do with this server.

Verizon is consistently rejecting mail from the server, and sent me this
checklist to verify:

1.) Please ensure that your server is accepting mail from
206.46.252.0/24.

2.) Please ensure that your server accepts a Null Mail From: command
e.g. Mail From:<>.

3.) Please ensure your mail server responds to the SMTP commands within
30 seconds.

4.) Please ensure the from address used is a valid email address that is
accepted by the MX server for that domain.

5.) Please ensure you have a proper MX record.

Does any of this apply to the webserver? The SMTP Service wouldn't have
anything to do with the functionality above, right?

Do I need to use a smart host instead of sending directly from the server to
get around verizon's restrictions?

Huh? Aren't you asking why your SMTP doesn't work with Verizon
addresses? Or did I miss something?

Did you chekc each of these items?

What restrictions? All they say is have your email server setup
properly...

The webserver is not a mailserver. There's no incoming SMTP enabled, so it
wouldn't meet any of the requirements above. There's an MX record for the
domain, but it has nothing to do with this server.

But this isn't the mailserver for the domain, it's just a webserver that
sends out emails when someone fills in a form on the website.

Duh... did you think *HOW* the web server sends emails? It uses a SMTP
server, that's how!

And *WHAT* SMTP server is the web server using to send these emails?

I understand that...thanks for the LART.

So if I understand you correctly, I would have to allow incoming SMTP on
TCP/IP 25 to the webserver, so that Verizon can verify the origination of
the email?

Up until now, the only ports allowed from the firewall to the IP of the
webserver are 80 and 443.

I'd rather keep my servers as locked down as possible, so it seems like I
would have to route mail from this server through a smarthost...no big deal,
but a PITA to manage since I have a lot of servers to deal with.

You don't get it, and I'm not able to communicate this to you: THE WEB
SERVER IS NOT SENDING THE EMAIL, THE SMTP SERVER IS. Whichever SMTP
server your web server is tied to is the one you need to work on. Web
servers DO NOT SEND EMAIL. Ever.
