    Hi all,

    I was following the tutorial on DKIM setup and all was going well until I actually started the services: My maillog becomes flooded with this error:

    Sendmail DKIM Filter: Unable to bind to port inet:[email protected]: Address already in use
    Jul 22 19:43:20 ookblah dkim-filter[23539]: Sendmail DKIM Filter: Unable to create listening socket on conn inet:[email protected]
    Jul 22 19:43:20 ookblah dkim-filter[23539]: smfi_opensocket() failed

    I checked the permissions on /var/run/dkim-milter and its chmod 700, but i don't see a dkim.sock file in there. Coudl anyone point me int he right direction? Thanks.

    looks like something is allready runing on that port so u can't bind it again,

    post with netstat -tap so we can see whats up from services on your system

    This is the result of my netstat -tap

    Thank you for the help, I no longer get the socket errors. However, when I try to send a test e-mail I get this error:

    warning: connect to Milter service inet:localhost:20207: Connection refused
    Jul 24 00:31:12 hostname postfix/cleanup[7436]: 585DAF8347: milter-reject: CONNECT from localhost[]: 4.7.1 Service unavailable -
    try again later; from=<[email protected]>

    Something else is listening to that port run the command

    netstat -nalp
    To see what is listening to the port
