amavisd is adding the following header to my mails :
Authentication-Results: my.example.com (amavisd-new); dkim=neutral reason=”invalid (public key: DNS query timeout for their._domainkey.example.com)” header.d=example.com
The problem is that this is not quite true !
I have no DNS problems, e.g. if I do :
dig their._domainkey.example.com TXT
dig returns fine without any substantial wait.
What setting am I missing ? Where am I going wrong ?
