Exchange 2003 re-enabling incoming email after being used as a mail relay for spamers.
We have a 2003 small business server that was used in a mail relay spam attack. I did at least the following to disable mail relaying.
- I deleted the internet smtp conection
- changed the admin password
- disabled the security for anomyous and everyone
- turned off IUSR and IWAM accounts
Now I think I have re-enabled all of those
I created a new SMTP connector and unchecked mail relaying.
I am currently able to send mail but not able to recive mail, and when I go to dnsstuff.com I get the following error: this is the right ip address for our exchange server.
tdmconsulting.com. - 71.16.73.108 [Could not connect: Got an unknown MAIL FROM response: 454 5.7.3 Client does not have permission to submit mail to this server.
What I am thinking is happening is I disabled anonomus connections to the server in one of 100 possible locations, please give me some ideas of where to look, to open the server back up.

DNSReport.
Mail FAIL Connect to mail servers ERROR: I could not complete a connection to any of your mailservers!
tdmconsulting.com: Timed out [Last data sent: MAIL FROM: ]
If this is a timeout problem, note that the DNSreport only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.

How to Configure a Virtual SMTP server
Opposite is a diagram to help you navigate to the various Virtual Servers folders. Once you have found your Exchange 2003 server object, expand the Protocols folder. Each protocol has its own Virtual server. SMTP for MAPI clients (Outlook), HTTP is for OWA (Outlook Web Access).
We are most interested in the Default SMTP Virtual Server. As its name suggests, this is the container where you check settings for regular SMTP mail. (See this SMTP server object at the very bottom of the screen shot.)

found it... couldn't figure out where I unchecked anonomus access

Ah well, all seems well now! MX records seem fine.
You may want to ask CS to edit your post above and remove the email address so the spiders don't index it and it doesn't get harvested by spammers!
