I can't understand what can i do please help me. Thanks Mohib
Setup a SPF records in DNS for your domain and enable DKIM (and set the dkim record in DNS too) if you have not done that yet. Then check if your IP address is on any blacklists, e.g. at mxtoolbox.com.
Thanks a lot till, I already set SPF record and enabled DKIM but not set dkim record ins DNS. Can you write how to create dkim record for my domain. Thanks again. Mohib
