Email source definitions represent metadata for emails or contacts stored on a mail server or in an Outlook PST file.

When the PowerCenter Integration Service extracts data from an email source, it converts the data based on the datatypes in the Application Source Qualifier transformation associated with the source.

You can import an email source in the Source Analyzer. To import an email source definition, you need to create a Data Source Name (DSN). A DSN contains information to connect to a mail server, such as the mail server name, protocol, user name, and password.

You can configure the DSN to import source metadata over secure protocols, POP3S and IMAPS. POP3S and IMAPS connectivity require a security certificate signed by the Certification Authority. The certificate needs to be in the keystore called cacerts. You can get the security certificate from your mail server administrator. A certificate is generally stored as a .cer file.
