What does this plugin do?

The RSForm!Pro Mailer Plugin allows RSForm!Pro to send emails using a different mailer settings than the ones from Global Configuration. Besides this functionality, the RSForm!Pro Mailer Plugin will help you to prevent spoofing by adding a digital signature to outgoing message headers using the DKIM standard.

DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain is authorized by that domain's administrators.

In technical terms, DKIM is a technique to authorize a domain to associate its name to an email message through cryptographic authentication.

Note: The DKIM option can be configured from the component configuration by heading to Components > RSForm!Pro > Configuration > Mailer Settings tab.
