>Note that advertising is inappropriate on the IETF mailing list. I don't think that was Vernon's or my intention. Then remove both Vernon's (DCC) and my post. I saw it as implemented examples of two different fundamental internet engineering ways of dealing with out of signal email. Both the DCC and ours are free services as best as I can tell, so don't know what the advertising would be for. The traffic here is miniscule compared to a link I can put on other sites I run and I would guess probably similarly for Vernon. Shelby Moore http://AntiViotic.com
