If you don´t have any SPF Records set at all yet for your domain please create the following record:

v=spf1 a mx -all

The SPF or Sender Policy Framework is intended to prevent the falsification of sender addresses in emails (spoofing). Specifically, the sending of e-mails via unauthorized mail servers should be prevented.

The receiving mail server can use the domain's SPF record to check whether the email received comes from an authorized mail server or from an unauthorized server. In the latter case, the e-mail can be identified via the SPF spam protection and declared as spam.
