SPF Records
An SPF record permits recipient mail servers to interrogate the Name Server for your domain name to determine if the source IP address of the mail is authorised to send mail for your domain name. If an SPF record exists and authorises the source IP address, the mail can be accepted by the recipient mail server. If an SPF record exists and does not authorise the source IP address, the mail can be bounced as it did not originate from an authorised source IP address for the senders domain.
Adding an SPF Record
Click 'Add SPF Record' to add an SPF record. On the resulting screen, specify whether you wish to permit our mail clusters and shared hosting accounts to send email on behalf of your domain by checking the relevant box. Specify which additional servers you wish to permit to send email on behalf of your domain by typing the IP address or server hostname, one per line. Specify whether you wish to restrict all other Internet servers from sending legitimate email from your domain by checking the relevant box. If you wish to define a TTL for the record, enter it in the box provided. If you do not define a TTL it will default to 86400 (1 day). If you are not sure what TTL is required, leave the box blank; the default is appropriate for the majority of cases.
Deleting an SPF Record
To delete an SPF Record, click its 'Delete' link, you will be asked to confirm the deletion before the record is actually removed.
Editing an SPF Record
You may change the parameters of an existing SPF Record by clicking the adjacent 'Edit' link, the description of the options when editing a record is the same as when creating a new record.
Please note: Many Mail Transfer Agents (MTA) have adapted to actively check for SPF records, however at the time of writing, SPF has not become an Internet standard. As such some un-configured mail servers will not read any SPF records set on your domain name.
