DKIM and DMARC set up on dedicate 1and1 server
<p>I am having a little trouble figuring out this process. I can manage to get the DNS records set up for the DMARC, DKIM and SPF. I get lost with what i am trying to do with the private key for the DKIM. Currently i am using a dedicated server offered by 1and1.com. if someone can give me a quick walk through i would really appreciate it.</p>

<p>The website i am currently making sends out scheduled emails plus emails on behalf of users. Some of them are being blocked by Hotmail and other email providers. I understand that adding these protocols will increase the likelihood that the emails reach their intended targets. If there are any other mechanisms that can accomplish this as well, i would greatly appreciate a heads up.</p>

<p>i use the built in php mail method to send emails (i do not want to incorporate a third party plugin to do something that php already does and works pretty well)</p>

<p>thanks</p>
