I'm not comfortable with this: the border between an end-client and a server is really unclean. Also, what about and end-client server? :) I don't understand the push toward using the ISP's mail server to send mail. I guess that an end-client may legitimally run its own mail server without relaing its outgoing mail to its internet provider. I can, however, well understand the need for a legitimate mx to be tied to a static address. That make sense for identification purposes. What's wrong with small businesses running their own mx? Just guessing: isn't that the blame about this originates from large ISPs that just want to tight their customers? ----------------------------------- Giampaolo Tomassoni - IT Consultant Piazza VIII Aprile 1948, 4 I-53044 Chiusi (SI) - Italy Ph: +39-0578-21100 MAI inviare una e-mail a: NEVER send an e-mail to: [EMAIL PROTECTED] > > > >> SORBS uses the following Internet Draft for determining > whether networks > >> are statically or dynamically by rDNS: > >> http://tools.ietf.org/wg/dnsop/draft-msullivan-dnsop-generic-namin > >> g-schemes-00.txt > > > > Right.
