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:       IN TXT   "v=DKIM1; g=*; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDaSlf0l7scGWVaOlPlPX4C8Mce

If 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 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

first. are you using yours DNS server or some VPS? there were trables that IPS DNS servers makes yours IN TXT entry to lowercase.

second. try to remove g=*

Check yours TXT records from outside your server,some external resource
