Sender ID and Sender Policy Framework (SPF)

When a mailbox provider uses SPF authentication, they compare the server that appears in the message header — also known as the long or internet header — to the sending servers that are listed in the Domain Name System (DNS) record for the “envelope from” address.

To authorize our system to send emails on your behalf, access the DNS record for your domain through your domain name registrar — such as GoDaddy, Network Solutions, or Name.com — and add a TXT record to it for your SPF information.

Note: Add a TXT record with SPF information for each domain you use to send email.

If your organization uses its own office email server and Blackbaud is the only ESP that sends email on your behalf, enter:

v=spf1 +include:outboundmail.convio.net +include:outboundmail.blackbaud.net ~all

If your organization uses multiple ESPs, enter:

v=spf1 +mx +include:outboundmail.convio.net +include:outboundmail.blackbaud.net ~all

Tip: Don’t forget to also include the other email servers that are authorized to send on your behalf.

Sender ID and Sender Policy Framework (SPF) are two methods of email authentication that enable organizations to specify which mail servers are authorized to send email in their name. While both are similar, Sender ID is actually a variation of SPF developed by Microsoft.
