Sendmail Macros

Hello,

I’ve just inherited a Mimedefang/Spamassassin/Clamav setup
and it is
working fine. I’ve been asked to disable spam checks for
outgoing messages
and I thought to use the SMTP_auth to do so (as per the man
page), but yet
even after calling read_commands_file I still cannot get the
value of the
auth login used (or even defined as a variable). All I know
is that some
time ago the sendmail configuration was changed to use the
greet delay
(and other initial delays) to slow down the surge of spam
happening at the
time. I am lost on this. Any assistance would be
appreciated.

SMTP-auth'd mail can be identified by
$SendmailMacros{"auth_type"}
being defined.  You don't need to see what the value is.

You might assign to a variable in Mimedefang like this:

    undef($good);
    if (defined($SendmailMacros{"auth_type"})) {
        $good = 1;
    }
    if ($RelayAddr eq '127.0.0.1') {
        $good = 1;
    }

Undef, so the value is not carried over from the previous
message.
Call smtp-auth'd mail $good.
Call mail from localhost $good.
Maybe call mail from certain other hosts $good.

Then below this you can test for $good before applying a
filter routine
like Spamassassin.
