Re: DKIM sign only unsigned

[Damian]

I don't. Advise?

client IP does not work since the same IP sometimes send signed, sometimes

unsigned mail.

That's why I ask about only signing mail that is not signed, or, skipping
mail that is already signed (with valid signature).

Along the lines of:

$enable_dkim_signing = 1;
$enable_dkim_verification      = 1;
@author_to_policy_bank_maps    = 'HAS_VALID_DKIM';
$policy_bank{'HAS_VALID_DKIM'} = { enable_dkim_signing => 0 };
