I have Postfix installed on Debian Unstable, as the title states, the system is completely up-to-date, I have tried to get DKIM signatures working on outgoing mail using dkim-filter 2.8.2.
I couldn't use the default Debian way of doing things with sockets, instead I used the Ubuntu way:
I have the following in my postfix/main.cf
milter_default_action = accept
milter_protocol = 6
smtpd_milters = inet:localhost:12345
non_smtpd_milters = inet:localhost:12345
All is fine except I get the following message I start DKIM in mail.log:
dkim-filter: can't configure DKIM library; continuing
And when it tries to sign mails I get the following error:
postfix/cleanup: warning: milter inet:localhost:12345: can't read SMFIC_EOH reply packet header: Success
And then dkim-filter daemon stops.
I've looked through Google but found no actual way to fix this that works for me. I have this working fine on an Ubuntu server but would love to get it working on Debian too.
