Man, no way you got a valid domain, that's what that NXDOMAIN thing means. You gotta rap with your cable company on this one, man, 'cause there's nuthing we can do about it, 'cause this is pure sendmail, ain't got nuthing to do with openbsd. Ya need a static IP and an MX record for yer mail domain, so that's what ya tell your cable company, don't confuse them with openbsd unless they're real hip. Also, check out

plus do a google search on

'cause ya really gotta grok MX records to get this one right. Say, man, didja google on

        'Sender domain must exist'
