Scott, A took some time and went through the log and found that the following was true on all the ones I checked (around 50) entries, the following examples were found using dnsreport.com about the Warnings: Getting MX record for mail3b-better-health.wsol8423.com... Received an NXDOMAIN response OR Getting MX record for atkingroup.co.uk... Received a response code of 2.
This should be treated as an ERROR (per RFC974), and the E-mail delivery should PROBABLY be retried later I found 1 or 2 that did show an entry listed in dnsreport, however, I could not connect to them via telnet or nslookup's Keith -----Original Message----- From: R.

Actually, the "server failure" should indicate that your DNS server is broken, so it definitely should *not* return the server failure unless it is broken, or *perhaps* if it receives a server failure from the remote DNS server. Declude JunkMail is asking BIND if the domain has an MX or A record -- so if it returns a server failure when it should not, it is hurting your spam control. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
