Re: [CentOS] help with sendmail closing relay

on 6-4-2010 8:10 AM Jerry Geis spake the following:

I have centos 4.8 i686. It has stock sendmail. see file below.

I am getting reports that it is an open relay. I have searched all around and it seems like it should be closed. I have dnl for accept_unresolvable_domains.

What can I do to close my sendmail. Thanks,

Jerry

<snip> I know the m4 processor is very picky that things are in order.. http://www.sendmail.org/m4/intro.html

The general rules are that the order should be:

VERSIONID OSTYPE DOMAIN FEATURE local macro definitions MAILER LOCAL_CONFIG LOCAL_RULE_* LOCAL_RULESETS

If they get out of order, the m4 processor drops stuff
