Synopsis

How to configure a Sender Policy Framework (SPF) record (Exchange 2019).

You must have a Sherweb 2019 hosted Exchange account

The Sender Policy Framework (SPF) is a technical method to prevent sender address forgery.

Note : this configuration has to be done on your PUBLIC DNS server, which might be managed by a hosting provider.

Make sure you transmit the correct information to be added:

Type of record: TXT
Hostname: Leave the entry blank
- In some instances, you may need to put @ instead of leaving it blank
Value: v=spf1 ip4:173.46.152.128/25 ip4:199.244.76.0/24 -all
