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.

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.

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)

thanks

Yes, you can set DMARC on 1and1. Set:

Type:    txt
Prefix:  _dmarc
Value:   v=DMARC1; p=none; sp=none; rua=mailto:yourmail@hotmail.com;     
         ruf=mailto:yourmail@hotmail.com; rf=afrf; pct=100; ri=86400;

Change the 2 emails

  • Thanks, I did this on 1and1 just now, and it passed the test on http://mxtoolbox.com/domain/mydomainname.com/?source=findmonitors . My settings are Prefix: _dmarc, Value: v=DMARC1; p=reject; rua=mailto:admin@mydomainname.com – mdiehl13 Aug 14 '16 at 06:41
  • That's good to know they allow it now, send an email to `mailtest@unlocktheinbox.com` and make sure you have no critical issues. – Henry Aug 15 '16 at 13:33

You can't set up DMARC or DKIM on 1&1 DNS, they don't allow underscores (_) in sub-domains in their DNS records.

Sorry for the bad news. They are the only hosting provider I know about that doesn't allow underscores (unless something changed recently)

DMARC is easy to set up just use this DMARC Wizard

DKIM is something that you need to set up with email software program you're using to send mail (which you didn't tell us what you're using) - I'm guessing postfix or exim?

  • i actually got all of the DNS settings fine that was the easy part. From there i am totally lost. I am not sure what i am using to send email (the default settings/ 1and1's own emailer) I looked up phpinfo() and it does not mention either exim or postfix. Should i configure one of the two? –  May 31 '16 at 15:15
  • i also should mention i opted for the 1and1 managed dedicated server. im not sure if this will have an affect –  May 31 '16 at 15:34
  • i think i should still be able to adjust the server settings using PuTTY –  May 31 '16 at 16:02
  • What's your domain name so I can check the DNS. – Henry May 31 '16 at 17:40
  • i removed the DNS settings last night when i was tinkering but i checked the records on http://mxtoolbox.com/ and it recognized them. I think i only have the SPF record still there –  May 31 '16 at 17:51
  • Yeah, configure either exim on postfix and make sure you select the default option according to this document: [Email with 1&1](https://help.1and1.com/servers-c37684/dedicated-server-linux-c37687/organization-via-control-panel-c37695/e-mail-options-for-1and1-servers-a650143.html). Once you get that set up and your DNS configured, then you can proceed to the next step. Also if your testing DNS proprogation use this [DNS Tool](https://www.unlocktheinbox.com/dnstools/mx/) it allows you to select different servers to query DNS from. – Henry May 31 '16 at 18:55
  • I just tried on 1and1, they didn't let me use prefix 'dmarc' but they did allow '_dmarc'. I then checked on mxtoolbox.com, and it said my DMARC was correct. – mdiehl13 Aug 14 '16 at 06:45
  • Looks like 1&1 now supports underscores in sub-domains now, but they sure don't provide much info beyond that – Gerry Jul 15 '20 at 18:19
