Re: Use one DKIM key for all mail domains not work

DKIM in iRedmail/Amavis stopped working for us some months ago. There seems to be a problem with newer Postfix and/or amavisd versions (> Postfix 3.4, > Amavisd 2.11).

I could never get it debugged, so we switched to OpenDKIM a long time ago and integrated it into iRedmail.

Re: Use one DKIM key for all mail domains not work

With this setting, Amavisd will sign the DKIM key for all outbound emails. Just that simple smile

dkim_key('mydomain.com', "dkim", "/var/lib/dkim/mydomain.com.pem");

@dkim_signature_options_bysender_maps = ({
    # catch-all (one dkim key for all domains)
    '.' => {d => 'mydomain.com',
            a => 'rsa-sha256',
            c => 'relaxed/simple',
            ttl => 30*24*3600 },
});
