Oh? I don't know what I'm looking at:

This box is stock ubuntu, and i only use ssl, postfix and samba, so i'm
wondering what i did wrong. i'm not using sasl, tls or anything other
than postgrey added on.
should i just remove postfix and re-install? is it safe to keep main.cf
and the files i created/modified (transport, recipient_checks,
whitelist, helo_access, aliases and virtual)?
Thanks!
