Hello guys,

Am trying to install and configure SPF and DKIM but my emails still go to spam.
Find below headers from gmail and yahoo response.

I am running on CentOS 6.5 64bit, Zpanel, Roundcube for my emails

Kindly help on how i would solve this error "dkim=neutral (bad version) header.i=@"

I used this tutorial to configure my dkim http://www.prosinger.net/index.php/opendkim-postfix/

I have replaced my domain name with xxxxxxxxxxx.com and my IP address with 000.00.000.000 for
the purpose of asking this question.

I have also set my DNS records as follows:

TXT    @   "v=spf1 mx -all"

and

TXT    mail._domainkey  "v=DKIM1; g=*; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC13SVMhSMOFNrAco7J0W6o1FvOVzfkYqRWVB2OrE6voPR68Q+DMPoVs3IPhs971cbGAvZRduQ2cspbblnf2mlhtpCphe8s0ox4CeZPVR0sR2lmXxrWnZmflALmpsHuIvNVQ3dJT/EI3Vy59t9VOxZ0zByMGgRD5SEVb++++++xhBLwIDAQAB"
