I don't know if this has come up before, but it just came to my attention that there are some mail servers which check rDNS of domain MX records before accepting emails. I don't believe spamdyke does this.
Is this a total waste, or would it perhaps catch some spammers? Some domains have many MX records. I wonder if all MXs are checked, or only the highest priority? Seems like a bit of a waste of resources to me. Any thoughts about this? (I'd certainly prefer to see SPF implemented than MX rDNS checking!) Thanks Sam (and everyone). -- -Eric 'shubes' _______________________________________________ spamdyke-users mailing list [email protected] http://www.spamdyke.org/mailman/listinfo/spamdyke-users
