SPF (Sender Policy Framework) is an email-authentication technique, which allows the domain owner to control who can send messages on behalf of the domain.

DKIM (DomainKeys Identified Mail) is an email-authentication method, which ensures that message's subject, sender address or content has not been tampered with during transit.

Properly set up SPF and DKIM signal the recipient's mail server that the message is authentic and from a legitimate source, which in turn improves domain reputation and can improve deliverability.

Adding SPF record

On the domain nameserver management page.

1) Add new TXT entry, if no SPF entry can be found:

Name: (leave empty)

Type: TXT

Value: v=spf1 a mx include:_spf.smaily.com ~all

2) Update the existing one, if already present:

Add "include:_spf.smaily.com" before "~all" or "-all".

Note! SPF entry has to contain IP-addresses of all of the services that are used to send messages on behalf of the domain. Otherwise messages might not get delivered to intended recipients. If you are unsure of which services send messages on behalf of your domain, please consult with your IT department.

Adding DKIM records

To enable DKIM signing, you need to add two CNAME records:
