Background
GMail, along with a number of other email platforms, are insisting on stronger email credentials: setting an SPF Record for your domain is an absolute essential now, but DKIM and DMARC are becoming increasingly relevant.
We have been advising customers on the set up of SPF Records for over a year now, and this has fixed delivery issues in 100% of cases so far.
Take a look at our Service Alert on SPF Records.
In order to build upon this, we can announce that we now support DKIM.
DKIM Implementation
DKIM, or DomainKeys Identified Mail, is an email authentication method that uses a digital signature to let the receiver of an email know that the message was sent and authorised by the owner of a domain.
Direct Customers:
DKIM is already enabled. Log into your Control Panel using your Primary email address and password, go to Domains and select the relevant domain from your list. You will then see the required DNS settings to support DKIM – these will need to be added to your Domain DNS configuration using the Control Panel provided by your Domain Host.
Once this is done, start using mail.verygoodemail.com with Secure SMTP (port 465) to send your email.
Partners:
If you haven’t already, Partners/Resellers will need to contact us to enable DKIM. If DKIM is enabled for the Partner, then when a user goes into their Control Panel at account level and clicks on Domains, they’ll get a DKIM section that tells them the required DNS settings to support DKIM – these will need to be added to your Domain DNS configuration using the Control Panel provided by your Domain Host.
Once this is done, make sure your users are using Secure SMTP (port 465) to send their email. If you don’t have your own domain set up for this, then they should use mail.overssl.net
Zimbra:
Users can find DKIM info in main control panel (not Zimbra), or email us at support@verygoodemail.com for it.

DMARC Overview
DMARC requires the addition of some more DNS records, over and above a DKIM entry, that allow recipients to know where to report Spam. For an overview of DMARC take a look at the relevant DMARC FAQ.
