Setting up SPF

If your domain name used in the email addresses sender of your messages and it is protected by an SPF record, you must add our IPs to that record.

Just include the following record: _spf.mysmtp.com.au

Once updated, your SPF record should contain the highlighted passage of the following example:

600 IN TXT "v-spf1 a include:_spf.mysmtp.fr 'all"
