Viktor has allready answered you need to publish your dkim key in the your dns zone file looks like nameservers for lbsmtp.org are Name Server:ENOW.MARS.ORDERBOX-DNS.COM Name Server:ENOW.EARTH.ORDERBOX-DNS.COM Name Server:ENOW.VENUS.ORDERBOX-DNS.COM Name Server:ENOW.MERCURY.ORDERBOX-DNS.COM so there should be some interface for publish your dkim key and/or some admin which will do it for you , then sign your mail with i.e dkim milter service perhaps this will help https://help.ubuntu.com/community/Postfix/DKIM > > On Tue, Jul 17, 2012 at 8:21 PM, Viktor Dukhovni > <postfix-us...@dukhovni.org <mailto:postfix-us...@dukhovni.org>> wrote: > > On Tue, Jul 17, 2012 at 02:21:50PM +0530, Naval saini wrote: > > > This is my DNS ZONE file entry: > > > > _domainkey.r02.lbsmtp.org <http://domainkey.r02.lbsmtp.org>. > IN TXT "t=y; o=-;" > > The above resource record (RR) has no selector, it has no meaning in > DKIM. > > > lbsmtp.org._domainkey.r02.lbsmtp.org > <http://domainkey.r02.lbsmtp.org>.
