Outgoing email that is formatted for display in an email client program (such as Microsoft Outlook) may contain HTML markup, and is produced by correspondence rules with an EMAIL correspondence type. Outgoing email that contains only text can be produced by correspondence rules with a PHONETEXT correspondence type, and can be sent to a SMS-capable phone as a text message.
If your server can access a keystore with an appropriate certificate, your application can send digitally signed email using the standard activity @baseclass.SendEmailNotification. See More about Correspondence rules.
If your application has email capabilities enabled, your application can initiate and process email-based conversations. When an email is sent, a key is generated and attached to the email. When the reply is received, the message is attached to the work item, and a copy of the message is forwarded to the appropriate party. This functionality is initiated using the standard Work-.SendEmailCorr local action, and requires an Email Account instance, Service Package data instance, Email Listener data instance, and a Service Email rule. (For an example of the service rule, review the standard rule EmailDefault.Work-.ProcessEmails.)
For more information, see the PDN article How to support email 'conversations'.
Perform approvals or other actions on work items using email-based work processing. Enable this functionality using a standard Notify activity and the correspondence name pzEmailActions, which applies to Work-, belonging to Pega-ProcessEngine RuleSet. The approver receives an email that contains hyperlinks to non-local flow actions. The approver clicks on the appropriate flow action and adds comments as needed, then sends the response. The email is received by an email listener that validates the response using the service activity pyCreateAndManageWorkFromEmail, then delegates processing to the pyProcessEmailRequest agent. A copy of the response is attached to the created work item. For more information see Understanding email-based work processing.
If your application is required to send encrypted email, encrypted emails can be sent by using the @baseclass.SendEmailNotifcation activity and selecting the EncryptMessage parameter. For an example, see PDN article How to send encrypted email messages.
When the system sends outbound email, if the connection to the email server fails, messages are automatically queued for resending later. The number of resend attempts made is defined in the Pega-ProcessEngine.pyEmailMaxResends system setting.
When a customer has a Connector rule for an HTTP-based protocol such as HTTP, SOAP, REST, and sometimes Email, they may point to an SSL-enabled ("https") endpoint. The service that is connected to will provide an SSL certificate in order to identify itself and secure the connection.
The Application Server verifies the certificate that another service provided. When Pega 7 Platform is deployed in tomcat, typically the default java trust store is in use. IBM Websphere has its own trust store, controlled in the Admin Console.
When the certificate provided by a service is not in the trust store, or otherwise not trusted (for example, it is out-of-date or issued to a different organization), the connection cannot be completed and an exception results.
Ensure that the application server's trust store is set up correctly.
