I use postfix to send outgoing emails ... a user does not receive sent posts ... when I sent same to my gmail account post does arrive in inbox ... yet below is what appears on Show Original

Authentication-Results: example.com (amavisd-new); dkim=neutral (1024-bit key) reason="invalid (public key: missing p= tag)" header.d=example.com

here is my DNS domain TXT record for dkim

dig +short TXT   mail._domainkey.example.com. 
"v=DKIM1;"
"k=rsa;"
"p=MIGfMA0GCSqGblahblahblahDCBiQKBgQC55gymo9hvcdVpZIXhsO2Gn2hjJdcngKfkab7sDoYV6lvZYe/4euT+JbMk2PUMeWyGuJdkhv+iGzO8CMwjWO9PMOfMZGC8zd4ID3q7dP7QplV93j4i20tMk9fHTQYi0KFI8CB6sDhIhqKgEaJi6PL9DRQlahV00n6DqeWPSzJQNQIDAQAB;"

any ideas ? Above format worked in the past just fine

I am sending email using github.com:tomav/docker-mailserver which runs in a Ubuntu 14.04 container where I host it on AWS using route 53

    I'm not familiar with the dig output, but if the above means 3 TXT records, and not one single record with 3 Strings, this is probably the problem. Only one TXT records per selector is allowed in DKIM. – user228011 Feb 15 '17 at 19:52
