This guy's system has a swell anti-spam technique that checks all of the sender's MX hosts for validity, where validity apparently means having an A record. A quick check of mail6.iecc.com will reveal why it doesn't have an A record, and why this complaint is particularly silly. R's, John Diagnostic: 2001:06b0:0008:0002:0000:0000:0000:0203 does not like recipient. Remote host said: 554 5.7.1 Sorry; <[email protected]> has an invalid MX record: MX Record: mail6.iecc.com does not resolve. Giving up on 2001:06b0:0008:0002:0000:0000:0000:0203.
