i see same problem with 127...
Authentication-Results server.yamera.de; spf=pass (sender IP is 127.0.0.1) smtp.mailfrom=[email protected] smtp.helo=h2968871.stratoserver.net
Received-SPF pass (server.yamera.de: localhost is always allowed.) client-ip=127.0.0.1; envelope-from=[email protected]; helo=h2968871.stratoserver.net;
Changing between: Send from domain IP addresses and use domain names in SMTP greeting / Send from the specified IP addresses dosnt change anything. Can`t figure it out why "smtp.helo=h2968871.stratoserver.net" hijack the headers. @Peter Debik - is there some hidden option to change this?
