The mailing list for listmasters using Sympa

[Peter Polkinghorne <address@concealed>]

I do not know which version you are running, but these code fragments from 
6.0.3 indicates possible causes:

  
    ## Ignore messages that would cause a loop
    ## Content-Identifier: Auto-replied is generated by some non standard 
X400 mailer
    if ($hdr->get('Content-Identifier') =~ /Auto-replied/i ||
        $hdr->get('X400-Content-Identifier') =~ /Auto Reply to/i ||
        ($hdr->get('Auto-Submitted') && $hdr->get('Auto-Submitted') ne 'no')) 
{
        do_log('notice', "Ignoring message which would cause a loop");
        return undef;
    }

And

    my $conf_email = &Conf::get_robot_conf($robot, 'sympa');
    my $conf_loop_prevention_regex = 
$list->{'admin'}{'loop_prevention_regex'};
    if ($sender =~ /^($conf_loop_prevention_regex)(\@|$)/mio) {
        do_log('notice', 'Ignoring message which would cause a loop');
        return undef;
    }

Which by default is (Default value: 
mailer-daemon|sympa|listserv|majordomo|smartlist|mailman)

We had an issue with messages with an auto-submitted header - the newer 
versions of Sympa allow you to permit such messages.

Subject: [sympa-users] Message which cause a loop... What is this?

Hi again!

We have a problem with some lists. Sympa logs is this:

Dec  9 08:58:54 localhost sympa[17426]: main::DoFile() Ignoring
message which would cause a loop
Dec  9 08:58:54 localhost sympa[17426]: Moving bad file
address@concealed to bad/

I have look at the members of the lists and thay are only 4 valid
members, with individuals address. What is this loop which Sympa is
loggin about?

Thanks!
