I think this hint worked. At least my mails are signed now and I hope I did not mess anything with the settings I made in my amavisd.conf (I just used a subset of your parameters):
Code:
# policy bank to have mails DKIM signed
$policy_bank{'ORIGINATING'} = {
# indicates client is ours, allows signing
originating => 1,
# force MTA to convert mail to 7-bit before DKIM signing
# to avoid later conversions which could destroy signature:
smtpd_discard_ehlo_keywords => ['8BITMIME'],
# forward to a smtpd service providing DKIM signing service
# (if using a signing milter instead of signing by amavisd):
forward_method => 'smtp:[127.0.0.1]:10025',
virus_admin_maps => ["virusalert\@$mydomain"],
spam_admin_maps => ["spamalert\@$mydomain"],
};
# Use ORIGINATING policy to enable DKIM signing
$interface_policy{'10024'} = 'ORIGINATING';
Can anybody confirm that I did not make a big mistake by chosing these parameters.
