RSForm! Pro External Mailer 3.0.2

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.

The RSForm!Pro Mailer plugin configuration can be done from Components > RSForm!Pro > Configuration > Mailer Settings tab.

Within this tab are available the following options:

• Select mailer:
  • Use Joomla! Global Configuration - when selecting this option RSForm!Pro will use the mailer settings from Global Configuration in order to send emails
  • PHP Mail
  • Send Mail
  • SMTP - this option is used in order to set up an external mailer (such as Gmail or Yahoo)
• Enable DKIM?: No/Yes - enable or disable DKIM signing
• Domain: this field should contain your domain;
• Selector: to support multiple concurrent public keys per signing domain, the key namespace is subdivided using "selectors". For example, selectors might indicate the names of office locations (e.g., "sanfrancisco", "coolumbeach", and "reykjavik"), the signing date (e.g., "january2005", "february2005", etc.), or even the individual user.
• Passphrase: used to encrypt the private key
• Identity: this can be in the format of an email address, typically used as the source of the email
• Private Key: your private key must be inserted here. You can generate one from here: dkimcore.org
• Public Key: your public key must be inserted here. You can generate one from here: dkimcore.org

Note:

You cannot use field placeholders when configuring Custom Email Headers, the values needs to be added manually in the "Name" and "Value" fields.
