Hi, 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 ? Thanks ! Tim
