Might be worth looking into.
I doubt that this is the problem, as the client's IP would be nat'd to a public address. (Sorry Jake) ;) I'd check to see if the client's public IP isn't on an RBL. The smtp log should show you if it's being rejected, providing you know the address: # qmlog -lc "public\.ip\.of\.client" smtp > As far as increasing the number of smtp connections - look at > /var/qmail/control/concurrencyincoming to adjust that: > http://wiki.qmailtoaster.com/index.php/Concurrencyincoming > You may also want to look at increasing your mysql connections as well, > as by default I think it's set at 150 or so. > -- -Eric 'shubes' --------------------------------------------------------------------- QmailToaster hosted by: VR Hosted <http://www.vr.org> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
