My understanding is that blacklisting is done by IP address. Go to www.dnsstuff.com. They have a great tool for checking your IP address against spam lists.
To fix the problem you must set your SMTP Security to either "relay for addresses" or "no mail relay". Either way, your users will have to set their email client to use SMTP Authentication in order to send mail. This is the best way. Troy D. Hilton SofWerks LLC.

Schoenly Sent: Thursday, September 12, 2002 1:31 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] Determining if a domain/server is BlackListed for spam This question probably gets asked frequently, but I'm new to the list and I couldn't find a precise answer in the archives. I'm pretty certain that one or more of our domains have been BlackListed by SpamCop and some ISPs for previously being open relays. When this occurs, is the blocking done by domain name, mail server name, or IP address? Our Imail rep mentioned that Scott Perry has previously posted a way to search to see specifically which, if any, of your mail servers/domains are being blacklisted. Scott, can you point me to that resource? Finally the obvious question: what's the best way to remedy the situation?
