I have a 2wire Home Portal Modem/Router with a switch. I have setup a Windows 2000 server with Exchange 2000 and IIS 5. I have a dynamic ip from SBC Yahoo DSL and use Zone Edit. I have a dynamic DNS client to keep Zone Edit up-to-date. On the Windows 2000 server I have Exchange 2000 and Active Directory witch installs DNS.
In Zone Edit I have created a web site just fine and it works. I have also created a MX record which point to my domain the FQDM and created a A record witch points to it. The problem is that all my email from my domain are reconzied as spam, or in yahoo as bulk email. But when I use my SBC Yahoo DSL account in Outlook 2000 I can recieve them. When I send from my domain to my AOL account it does not recieve the email. My question is how do I setup a smart host of some kind to go through my ISP, SBC Yahoo DSL, to make AOL think I am not spam.

Hiow are you sending mail from your Exchange server?

If you are using dynamic DNS, you might need to check that your DynDNS provider also updates the reverse record for your host whenever you pick up a new IP, otherwise, the reverse lookup that most mail systems perform will fail and your smtp gateway will be regarded as a potential spam host.

this is what www.dyndns.org say on the subject -
Some ISPs, like AOL, are blocking my e-mail - what can I do about this?
Many providers block e-mail coming from a dynamic IP address. To solve this, you can relay all of your outgoing e-mail through your ISP's mail server. Simply set the SMTP/outgoing mail server in your e-mail client, or use an option in your local mail server such as Sendmail's "smarthost" option to force all mail to be relayed through that server. Consult your application or server's documentation for more specific details of how to do this. If your ISP does not provide a server for relaying, or if you need to relay while outside your ISP's network, check out our MailHopSM Outbound service.

The prices for their mailhop service seem quite reasonable.  This would enable you to specify their mailhop host as your smarthost.

I am still a little confused. So on my server I can set up Outlook 2000 to my ISP
SMTP address and my PoP3 account to my server or I can just set my smart host
to my SBC Yahoo DSL SMTP host address. I have tried setting up a smart host at
smtp.sbcglobal.yahoo.com and it did not get my emails to recieve on my AOL account when using dial-up.

The Yahoo SMTP gateway is most likely refusing to relay for your domain.  It may only relay for yahoo owned domains, regardless of whether you are connecting from an ISP assigned IP or authenticating.  This is where the dyndns solution comes in...

I have found some pretty cool stuff at http://postmaster.info.aol.com/.
This explains how AOL handles mail. It appears that it ony blocks Exchange Servers that are an open relay. I dont think that it will block a set of ips from
your DSL provider. You also have to have reverse DNS and with ZoneEdit I think you can do it but you have to calculate it with you dynamic IP address and the subnet mask, mine being 255.255.255.0, that the SBC told me they use for my
residental DSL.            IF anybody has anymore info please let my know
THANX

I finally figured it out!!!!. To setup you own (web server-exchange server) on a dynamic ip you have to use ZoneEdit to configure your zone and MX records.
Then you have to use a program like No-Ip.com(very useful) to configure a smart host. The program is called Alternete-Port SMTP. Then on the Exchange server have NO DNS forwarders and no DNS forwarder in the SMTP Virtual Server delivery advanced tab. In the SMTP VS delivery advanced tab set the NO-IP host that they assaign you and in Outbound Security put the basic authentication password to what they gave you. Last you have to change the port
on Outbound Connection tab.  


FOR ANYBODY trying to setup there own web-email server for 25.00 dollars this is how you do it with a residential dynamic DNS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
