dkim signature not present or bad format

Question

I'm going mad with dkim-filter + postfix. My message are signed but Gmail notify me errors like "dkim=neutral(no signature)" or "dkim=neutral(bad format)"

I don't know what is wrong. I've generated public and private key, and I'm using the right selector. My dns entry looks like that:

default._domainkey.accessdev-mail.com.       IN TXT   "v=DKIM1; g=*; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDaSlf0l7scGWVaOlPlPX4C8Mce
v3C7QpDBdwcJ+rw36GVlcJaJ2QU2yfh/VXr81DhmNbmBGyCH8EzK/FT42vAw7rp3

If accessdev-mail.com is your real domain, your DNS is in bad shape. The DNS servers according to `whois` are `SD2.ACCESS-DEV.FR` which returns no results for any queries (including SOA) about the accessdev-mail.com domain, and `SDNS2.OVH.NET` which I can't seem to get that TXT record from. — DerfK, Apr 20 '11 at 15:17
Note that if you send the e-mails out via PHP mail() this could be causing trouble as well. Unfortunately I cannot remember exactly what fixed it and the server I used it on does not exist any longer. — Frands Hansen, May 26 '11 at 13:24

Can you check yours dns records from external source with dig or nslookup by txt fields? – MealstroM Apr 22 '11 at 10:52
