    Hello,

    I have setup an email server using your guide here

    http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-roundcube-ubuntu-6.06

    All was working ok until i installed the dkfilter using your tutorial here

    http://www.howtoforge.com/postfix_dkfilter_domain_keys_implementation

    I can login and receive emails (recevied emails have a dkfilter header) but i cannot send them. Im getting this error in the mail log

    Code:
    Feb  7 12:12:07 bemail1 postfix/smtpd[8426]: connect from localhost[127.0.0.1]
    Feb  7 12:12:07 bemail1 postfix/smtpd[8426]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory
    Feb  7 12:12:07 bemail1 postfix/smtpd[8426]: warning: localhost[127.0.0.1]: SASL LOGIN authentication failed: generic failure
    Feb  7 12:12:07 bemail1 postfix/smtpd[8426]: disconnect from localhost[127.0.0.1]
    

    this is my master.cf

    As you can see from the error this has nothing to do with the dk-milter, it is your SASL server that has died.

    But if i remove all the settings that i added from the dkfiler tutorial, and restart postfix, i can send and receive emails fine.

    Hi,

    Well ive been playing with it, an i think i found the error. I had to change the smtp line in my master.cf

    here is the line i changed in the master.cf

    Code:
    # Before-filter SMTP server. Receive mail from the network and
    # pass it to the content filter on localhost port 10025.
    #
    #smtp      inet  n       -       n       -       -       smtpd
    smtp      inet  n       -       -       -       -       smtpd
        -o smtpd_proxy_filter=127.0.0.1:10025
        -o smtpd_client_connection_count_limit=10
    
    I now have the dkfilter header in my outgoing email :D

    Thanks for your help anyway topdog
