Not quite. Anyone using Marc's service or one like it (e.g. Postini) should DISABLE any SPF checks on their MTAs that reject mail, since their MTA is no longer the public MX for their domain. Marc can still perform SPF checks at *his* inbound MTA, as *he* is now their public MX. How he uses that information is up to him. Marc? I assume you tell your customers to disable any SPF checks on their inbound MTA once they start using your service? -- John Hardin KA7OHZ http://www.impsec.org/~jhardin/ [EMAIL PROTECTED] FALaholic #11174 pgpk -a [EMAIL PROTECTED] key: 0xB8732E79 -- 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79 ----------------------------------------------------------------------- Men by their constitutions are naturally divided in to two parties: 1.
