SPF record

This guide explains how to add or modify one or more SPF type records in the DNS zone (of a domain name) managed on the Infomaniak Manager .

SPF-type

The  SPF (Sender Policy Framework) record type is a standard for verifying the domain name of the sender of an email and aims to reduce SPAM.

Moreover, we use this type of registration automatically when creating a Service Mail on your domain (strict SPF):

• v=spf1 include:spf.infomaniak.ch -all

Thus the recipient server of the email you send will evaluate that any email not coming from our servers will be refused. This prevents malicious people from stealing email addresses from your domain name.

But you can also decide to modify the SPF for a more flexible model:

• v=spf1 include:spf.infomaniak.ch?all

In this case, the recipient server of the email you send will assess according to its own rules whether it accepts emails that do not come from Infomaniak servers.

To summarize:

• ? : the receiving server accepts the message even if the sender is not listed in the spf
• ~: the receiving server generally accepts the message if it is not listed in the spf but identifies it as suspicious
• - : the receiving server rejects the message if it is not listed in the spf (recommended)

Add SPF via TXT record

Consult this guide to know the procedure to follow in order to manage the records in a DNS zone.

Group several SPFs in the same TXT

To group multiple SPFs like in this example:

• v=spf1 include:spf.infomaniak.ch - all
• v=spf1 include:otherdomain1.ch ? all
• v=spf1 include:otherdomain2.ch ~ all

...just add a TXT according to this pattern:

• v=spf1 include:spf.infomaniak.ch include:otherdomain1.com include:otherdomain 2 .com - all
  

You can then remove the other spf entries from your domain's DNS zone.
