Hello Fred
As this is a filter, the choice made to use 'return-path' in place of 'from' is filter specific, not related to xmail To help you we need to know more about this filter, how it works, parameters, ... Self-written filter or found on the net ? Do you have source code for this filter (or can we get it somewhere) ? Francis -----Message d'origine----- De : xmail-bounces@...

Here is the problem, I am using a filter that works with SPF, everything is working fine except one thing.

Hi Francis,
Thanks for your reply. This is a self-written script that get the following arguments from filter.post-data.tab "!aex" "/mailsrv/MailRoot/filters/spfcheck/spfcheck.php" "@@FROM" "@@CRCPT" "@@REMOTEADDR" "@@FILE" The @@FROM is the actual variable that is checked by this linux command (from within a PHP script): exec("spfquery --name " . $this->_spfServer . " -sender=" . $this->_from . " -ip=" . $this->_remoteAddress . " -helo=" . $this->_helo, $output, $return); $this->_from == @@FROM Spfquery return a digit as the return code which is what I use for either dropping the email or let it go throught.
