The problem is not with you. All subscribers to the list received this. What causes the email is that conwin.ie use a lookup service to discard unwanted email (spam, scams, etc.). This lookup service seems to check with rfc-ignorant.com that has a listing over domains that are not compliant with the mail and dns related RFC's. Unfortunately febo.com is listed here. It seems febo.com (John's domain, and the host of the time-nuts mailing lists) was listed at rfc-ignorant.org 2 1/2 years ago due to a problem with the DNS record for meow.febo.com. | Current Results for febo.com lookup | blacklist_zone domain status Submitted Added Rejected | Removed | bogusmx febo.com Listed Nov 11, 2005 22:35 EST Nov 11, | 2005 22:35 EST Never Never ..and details: | Return Code: 5 | Description: ns1.febo.com reports that febo.com has an MX | (meow.febo.com) which ns1.febo.com says is a CNAME (to febo.com) The issue they're complaining about is that febo.com has an MX record that points to meow.febo.com. A host that is pointed to by an MX record must have an A record, and is not allowed to be a CNAME. It turns out that meow.febo.com is a CNAME for febo.com, and thus in violation with the RFC. --Magne _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
