    Problems with DKIM (Domainkeys) on Ubuntu

    Hi- I am having problems getting DKIM to sign my outgoing emails. I have DKIM successfully installed and it's not reporting any errors in /var/log/mail.log.

    I just sent a test message to a DKIM debugging service and got this reply:

    PHP Code:

    Do

    I think I have managed to get it working. However, there seems to be 3 lots of DKIM signatures in the headers (see below). Any ideas what could cause this?

    PHP Code:
    This message is an automatic response from Port25's authentication verifier
    service at verifier.port25.com.  The service allows email senders to perform

    free of charge, in the hope that it is useful to the email community.  While
    it is not officially supported, we welcome any feedback you may have at
