< rant > it really makes little difference. face it, email standards are now made by google, yahoo, aol, ... and shoved down our throats. have you seen the hoops one has to jump through to smtp over v6 to google? they outsource their alleged pain to the rest of the internet. my paranoid brother wonders if this is intentionally pushing small smtp sites to give up and use the mail cartel. but i think that is just collateral damage. randy
