Here is an updated "processdistsmtpline" function in RegexMain.pm that adds Distributed SMTP Login (LF_DISTSMTP) support for Postfix:

RegexMain.pm function processdistsmtpline on line 795

sub processdistsmtpline {
        my $line = shift;
        my $tline = $line;
        $tline =~ s/".*"/""/g;
        my @bits =split(/\s+/,$tline);
        my $ip;

        # postfix
        if ($line =~ /^(\S+|\S+\s+\d+\s+\S+) \S+ postfix\/(submission\/)?smtpd(?:\[\d+\])?: \w+: client=\S+\[(\S+)\], sasl_method=(?:(?i)LOGIN|PLAIN|(?:CRAM|DIGEST)-MD5), sasl_username=(\S+)$/) {

            if (checkip(\$ip) and $ip ne "127.0.0.1" and $ip ne "::1") {
                return ($ip,$account)
            } else {
                return;
            }
        }

        if ($tline !~ /^\S+\s+\S+\s+(\[\d+\]\s)?\S+ <=/) {return}

        if ($tline =~ / U=(\S+) P=local /) {return}

        }
}

Edit: Updated function to make sure that 127.0.0.1 and ::1 are skipped!

I know that I submitted this a while ago and I've updated the sample code for csf: v12.06. Would this still be possible to get this added in the next release?
