outboundmail.blackbaud.net SPF record: 1 DNS lookup, within the limit of 10

1 of 10 lookups

outboundmail.blackbaud.net uses 1 of 10 DNS lookups and is already within the limit.

You do not need SPF Guru for this domain today. The record below is offered in case you are about to add more senders.
1 void lookup comes from a macro 'exists:' mechanism, which is how a vendor answers 'not this IP'. That is expected and must not be removed, but it does permanently spend one of the two voids allowed.

is what a receiver looks up. Everything after the all is read by SPF Guru instead, and costs nothing.

See how this record behaves before you publish it. It opens with a documentation IP that matches nothing, which is what shows the lookup count; change it to one of your senders to see them pass.

Leave the rest of the record exactly as it is. Those mechanisms are what SPF Guru reads when it answers the query above. Delete them and every sender starts failing. How that works.
