Tips for sending emails

[smartmc]

Just thought I'd make a post to outline some tips for email security.

I've noticed that emails sent to Hotmail/Outlook get moved to the spam folder automatically, even if you are not blacklisted.

 

The solution is to make sure you use SPF, DKIM and DMARC.

 

HelioHost has DKIM support built-in, in Authentication page in the Email section.

If you intend to use Cloudflare, make sure you have enabled DKIM before changing to Cloudflare's nameservers, to make sure the TXT DNS record with DKIM information is copied.

 

SPF is pretty easy, and can be setup from the Authentication page in the email section, and will be copied if you setup Cloudflare at a later date. You can, however setup SPF after moving to Cloudflare, as no keys are required.

 

DMARC, as far as I'm aware, is not officially supported by HelioHost, but setup isn't too difficult. You'll first need to create an email address for reports to be sent to, then you can either read up on the syntax and write your own DNS record, or use an online generation service. I recommend the former, as it will give you better knowledge of how the technology works. After you have crafted the record, simply add it to your DNS zone as a TXT record, either through HelioHost or another DNS provider if applicable.

 

Thanks for reading, let me know if you think I got something wrong

I just use a dedicated provider for my email so I've avoided most of these problems.

 

SPF should be enabled however.

 

D: DMARC is not that hard, it can be set at the root domain.
