Definitions, as per Wikipedia:
Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing, a common vulnerability, by verifying sender IP addresses.
DomainKeys Identified Mail (DKIM) is a method for associating a domain name with an email message, thereby allowing a person, role, or organization to claim some responsibility for the message.
This is for tech people only. If they make a mistake editing their SPF records, they can block all their email sent from anywhere - including their own mail servers.
If you have a private domain that you use for your email (i.e. [email protected]) instead of a free email account with gmail or yahoo or another email provider, you may need to set up your SPF records to include BombBomb
SPF records serve to keep spammers or unauthorized senders from sending messages from fake email addresses created from your domain (i.e. [email protected]). Recipients can refer to the SPF record to determine whether a message purporting to be from your domain actually comes from your authorized mail server.
To add SPF records for BombBomb, just add 'include:bbemaildelivery.com' to your SPF record.
v=spf1 include:bbemaildelivery.com ~all
If they ask whether you meant a tilde or the squiggly, we suggest the squiggly because it's a soft fail and won't outright block anything coming from other places.
We do not currently support custom DKIM keys because we sign with our own.
