[SGVLUG] Postfix Rejections

[Rae Yip]

mydestination usually doesn't contain anything security sensitive; it
should refer to other variables that does.

And smtpd_recipient_restrictions and relay_recipient_maps? Those
shouldn't contain any hostnames. If you're setting these correctly,
then there shouldn't be a problem telling me.

Also, it's not clear to me if xxxxxx.tld is the server where postfix
is running, or another server to which mail should be relayed. If the
former, why bother messing with relaying? If the latter, why do you
have it set in mydestination?

-Rae.
