I learned from another to do it in amavisd after-queue content filter with a
policy bank that only does the conversion
$policy_bank{'FORCE_7BIT_MIME'} = {
originating => 1,
protocol => 'SMTP',
forward_method => 'smtp:[127.0.0.1]:12345',
bypass_banned_checks_maps => [1],
bypass_decode_parts => 0,
bypass_header_checks_maps => [1],
bypass_spam_checks_maps => [1],
bypass_virus_checks_maps => [1],
enable_dkim_signing => 0,
enable_dkim_verification => 0,
smtpd_discard_ehlo_keywords => ['8BITMIME'],
};
And
smtp:[127.0.0.1]:12345
is the 'next' smtpd listener in Postfix which then does the opendkim signing.
But like you say I think this does this for all messages not just for the
recipients that do not support 8BITMIME.
I dont understand how much of a problem that is.
And that uses amavis, which I do not use for anything else in authentication
any more. So it is a shame to have the whole amavisd just for this.
