Do you support a 2048 bit (or higher) Domain Key (DKIM)? More and more organizations are moving from the shorter 384, 512 and 768-bit keys up to 1024 and higher in order to protect against spoofing because the smaller keys are easier to crack.

Authenticate your email: SPF
Sender Policy Framework (SPF) shows that another server (e.g. salesforce.com) has permission to send on behalf of a whole domain (e.g. salesforceben.com) and is much stronger than a verified email address (which only proves that you had access to a single email address for a moment in time).
After SPF, along came another progression. DomainKeys Identified Mail (DKIM) shows that no one altered your email on route from the sender’s email server, to the recipient’s email server.
SPF shows that the sender is valid, DKIM shows that the email hasn’t been interfered with, but what about the rest of the emails that appear to be coming from your domain? Is it a forgery (just like anyone can print a letterhead) or should the email still be considered valid? Domain-based Message Authentication, Reporting and Conformance (DMARC) completes the set and tells the recipient email server what to do..
