So I would push the socket to scache after I'm done setting it up from SMTPD (auth, policy checks) and forget about it. If it times out before local smtp will start deliver then the client is welcome to reconnect. This will happen if it has to happen in SMTPD or in SCACHE the same way. In fact it's a descriptor passing tweaked for smtp deliveries. Nice! :) -- adrian ilarion ciobanu adria...@ciobanu.name http://pub.mud.ro/~cia +40 788 319 497
