I have sendmail and opendkim installed on ubuntu 14.04 and would like to configure DKIM.
Unfortunately sendmail refuses to sign outgoing emails with DKIM. Despite the fact that it already did before, but I commented it due to the fact that I did have to wait for DNS-entries to list the TXT-Record. Now I outcommented it, rebuild sendmail config and restarted sendmail and opendkim, but mail-tester.com claims that the messages are not signed.
Here is the entry for sendmail.mc:
INPUT_MAIL_FILTER(`opendkim', `S=local:/var/run/opendkim/opendkim.sock')dnl
check socket:
/etc/mail$ ll /var/run/opendkim/opendkim.sock
srwxrwxr-x 1 opendkim opendkim 0 Jan 9 03:07 /var/run/opendkim/opendkim.sock=
These are the log entries from mail.log at log_level 15

Mail.err does not show any problems. What else could I check to get it running? Thank you in advance for any help.
