Use Gmail's SMTP and IMAP with Workflow Notification Mailer

To configure Gmail's SMTP there are some prerequisites.

1. GMAIL SMTP require authentication. EBS started supporting authentication based smtp servers from R12.1.3 onwards.

    Please check below Note:

   Oracle Workflow Release Notes for Release 12.1.3(Doc Id 1095146.1)

    We may get error "Autentication failed" while sending notification. To solve this error we need to apply  patch 16559330 on top of R12.1.3

    Please check below Note:

    Workflow Notification Mailer Is Not Sending Email Notifications Or Goes Down When Authentication is Enabled (Doc ID 1528345.1)
