Are you using your severs mail program ( postfix, sendmail etc ) or are you using an external SMTP server.
I encountered the same issue with the while sending mail through an external SMTP server (mandrill).
I was able to fix my sender addresses by adding DKIM keys generated by mandrill to my dns data
