An SPF record , short for Sender Policy Framework , is a type of Domain Name Service (DNS) record that identifies mail servers authorized to send email on behalf of your domain.
The purpose of the SPF record is to prevent spammers from sending messages with spoofed sender addresses within your domain—that is, impersonating your sender even though they aren't a user in your organization with access to your email address. Recipients can check the SPF record to determine whether a message purporting to come from your domain is coming from an authorized mail server. Based on this check, they can decide whether to discard it as spam or accept it and deliver it to the recipient's email address.

Who should enter this SPF Record?
If you have mail handling with us, you have a correct SPF record in order to pass spam checks, see your mail delivered, and increase forwarding speed.
- If you have DNS management from us, if you don't already have it, we will enter the correct SPF configuration for free.
- If you don't have DNS management from us instead you will have to independently enter the following SPF configuration, or possibly ask our commercial advice to do so.
Managedserver.it uses only the following SPF configuration on all mail domains in our management:
domainname.it. IN TXT "v = spf1 include: hostalo.it include: managedserver.it include: managedserver.eu ~ all"
