OK.. What about this? aaa.com domain MX record that points to mx1.blah.com bbb.com domain MX record that points to mx1.blah.com ccc.com domain MX record that points to mx1.blah.com blah.com domain A-record for MX1 that points to the IP of the mail server, 111.111.111.111.. In the reverse zone only mx1.blah.com will show up under 111.111.111.111, but will mail still work from these 3 domains? What I really could use is a sample DNS entry for a domain/domains that are on a mail server that only uses one IP for many domains..

If you have MX records for "domain1.com" and "domain2.com" point to "mail.domain1.com" and "mail.domain2.com" respectively, you can have the PTR record for the IP address of the mail server be "mail.domain1.com". Or, if you have a need to, you could have 2 PTR records (which does NOT break RFCs), one to "mail.domain1.com" and one to "mail.domain2.com". However, this is pretty silly, as no software that we are aware of looks past the first domain name. >Here are stripped examples of 2 domains on the same mail server.

It would just be a PTR record for the IP address that resolves to mail.domain.com. It sounds like your problem is that you are using a DNS server that tries to decide for you what the DNS should look like, and isn't doing a very good job of it. You need to find out how to delete all the extra PTR records it has created, and add just the one that you do need. >Also, how many records will IMail grab in the reverse zone?? I don't believe IMail does any reverse DNS lookups. If it did, it would almost certainly just use the first record that is returned. -- -Scott Declude: Anti-virus and Anti-spam solutions for IMail. http://www.declude.com -- Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
