Sounds like this test might be a good negative weight test like IPNOTINMX. Of course if they use a good mailfrom it could reduce the positive. Any thoughts?

The standard MAILFROM test will check to see if the domain on the return address has either an MX or A record in DNS. So if an E-mail fails the MAILFROM test, the return address can't receive mail. The strict version (defined with the "mailfromstrict" test type) only checks for the MX record. Although a domain with an A record can receive mail (if there is a mailserver at the IP corresponding to the A record for the domain), it isn't advertising that it allows E-mail. It will have more false positives -- people seem to think there isn't a problem with having no MX record, since the RFCs do require mailservers to attempt to send to the A record if there is no MX record. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
