Does anyone know why the SMTP server for this list doesn't reverse resolve?
I'm thinking of turning on mandatory reverse resolve to cut down on the volume of junk hosts connecting from 184.108.40.206/8 and I noticed that doing so would stop delivery from this mailing list. Does anyone know if reverse DNS of a connecting SMTP server is outlined in any of the SMTP RFCs? If so, I'd like to reference the RFC in my error message. -Jeff
