It is not necessary to set up DMARC, but it is strongly recommended so that the
emails do not end up in the recipient’s spam folder.
With Domain-based Message Authentication, Reporting and Conformance (DMARC), the
domain of a sender can indicate that emails are protected by one or more authentication systems.
On the one hand, this gives the receiving server the assurance that the sender is authorized to send emails with the specified sender. On the other hand, it also defines what should happen to emails that are not correctly authenticated.
| Type | Name | Example |
|---|---|---|
| TXT | _dmarc | v=DMARC1;p=none; |
Extended configuration options
If you would like to receive a regular report on the compliance of the e-mails sent
, you can enter a corresponding e-mail address.
E.G:
| Type | Name | Example |
|---|---|---|
| TXT | _dmarc | v=DMARC1;p=none;rua=mailto:dmarc@DEINE-DOMAIN.CH |
Please replace dmarc@DEINE-DOMAIN.CH with a valid e-mail for you
For maximum protection against domain abuse, brand impersonation, phishing and
spoofing attacks, DMARC can also be set to “reject”.
This means that all
emails that do not have valid SPF and DKIM verification are rejected.
This
setting can also have an impact on other email senders such as Outlook or the
website.
Example value:
v=DMARC1; p=reject; rua=mailto:dmarc@DEINE-DOMAIN.CH;If you want to test the whole thing for the first time, you can also set the level to
“Quarantine”.
This instructs the recipient’s mail server
to move emails to the spam folder without verification.
Example value:
v=DMARC1; p=quarantine; rua=mailto:dmarc@DEINE-DOMAIN.CH;
