I can send email to AOL but cannot receive email from AOL.  The AOL senders inbox has a return email that says the error "550 requested action not taken:  mailbox unavailable 554 5.0.0 Service unavailable" . I am running Exchange Server 2003. Thanks.

Do you have problems with any other e-mail services besides AOL?

If you have no problems other than receiving from AOL accounts then it stands to reason that it isn't a problem with AOL. I would contact AOL and let them know that you are having problems getting e-mail from ONLY their users and no other and you want to see if there is a problem / block on their end.

Run SMTP diagnostics on the server with this utility:

Check to see if you have a SPF Record associated with your domain:

Check to see if you are on any SPAM Blacklists:

We changed ISP's here two months ago and I originally had trouble with both comcast and aol.  I figured out there was no pointer record for the new ip address so i had our DNS host add it.  Both worked fine until the last couple of weeks with Aol. I should say that at times an email will  come through from AOL but the majority of the time they bounce back.

Well, run the tests on those links that I posted and report back if anything is detected as out of the ordinary.

That is not uncommon, but just to be on the safe side you may want to publish an SPF record on your domain. This wizard is very easy to use and will walk you through the process.

When i am creating the SPF do i create it for our website and our mail server?  Our website is offsite and hosted by a third party but my mail server is here where i work with a different ip address.  The MX record is for our website and shows it points to our mail server with the mail servers ip address.

You would create it so it is associated with your domain that you receive e-mail on, but points to the IP address of the mail server.

does this look like a good SPF record?   v=spf1 mx mx:mail.domainname.com all
I run exchange in house and our website (domain) is outsourced.
