I have just created a workaround, so that mailman domains will not run as suexec/fastcgi, since that requires a very complicated configuration, if you have multiple vhosts running mailman:
Insert these lines into scripts/cron_task.inc.15.apache_fcgid.php instead of the line
if($domain['phpenabled'] == '1')
:
if(strpos($domain['specialsettings'],"/usr/lib/cgi-bin/mailman/"))
{
$php_options_text = apache::composePhpOptions($domain);
}
elseif($domain['phpenabled'] == '1')
