Just posted a message to Nabble's OpenEJB-Dev list, and recieved a 'Mail Delivery Failed' message that I thought might shed some light on the missing mailing list posts, http://mail-archives.apache.org/mod_mbox/openejb-dev/201010.mbox/%[email protected]%3e
The failure message contained a link to http://www.openspf.org/Why [url editted for privacy], which in part read nike.apache.org rejected a message that claimed an envelope sender address of myaddr...@mydomain. nike.apache.org received a message from kuber.nabble.com (216.139.236.158) that claimed an envelope sender address of myaddr...@mydomain. However, the domain MyDomain has declared using SPF that it does not send mail through kuber.nabble.com (216.139.236.158). That is why the message was rejected.
