# How to trust Signicat mail servers

# Introduction

Sender Policy Framework (SPF) records allow domain owners to publish a list of IP addresses or subnets that are authorised to send email messages on their behalf. The goal is to reduce the amount of spam and fraud by making it harder for malicious senders to disguise their identity. You can find more information on SPF on the Internet Engineering Task Force (IETF) website (opens new window).

# How to trust Signicat to send email messages on behalf of your domain

An SPF TXT record is used to verify the validity of a mail server. If a mail server is on the SPF trust list, emails sent from that server will have a higher (better) rating and will be less likely to end up in a spam folder.

In order to trust Signicat to send email messages on behalf of testdomain.com, you can include the following TXT record in the domain's DNS:

v=spf1 a mx include:_spf.signicat.cloud

Note

Any suffixes or additional SPF mechanics (like -all or ~all) will vary from DNS to DNS.
