The errors i was getting in the logfiles were:

dk_eom(): resource unavailable: d2i_PUBKEY_bio() failed
SSL error:0D06B08E:asn1 encoding routines:ASN1_D2I_READ_BIO:not enough data

After searching a while over the internet i’ve figured out i was getting this error because the selector TXT DNS record was incomplete. I am using ISPconfig3 with MyDNS and the MyDNS field in the ispconfig database was limited to 116 characters. The TXT DNS record had 230. I had to modify the database structure.

This error can also occur when you copy/paste the public key from your public key file to the dns record. Be careful not to have any white-spaces or line-breaks in it.

After fixing your selector wait for the dns to refresh so it’ll see your new dns record.

Hope this helps you out cause i lost half a day trying to figure it out.

As you probably know DKIM and DomainKeys require a long TXT record with a public key to be inserted in the DNS.

MyDNS started giving me problems when i was query-ing the DNS for this TXT record which has around 230 characters. MyDNS was crashing with the following log entry:

mydns: out of memory: Cannot allocate memory

The solution for this was replacing MyDNS 1.0.0 with the brand new MyDNS-NG ( Next Generation ) 1.2.8.26. Everything came back to normal now and It’s working like a charm.

You can get the mydns-ng 1.2.8.26 from here : http://sourceforge.net/projects/mydns-ng/
