EBS 12.2 Workflow Mailer – TLS + Authenticated SMTP (SMTP2GO) vs Relay Approach

Hi all,
We’re working with Oracle E-Business Suite 12.2 (on-prem), and recently lost our legacy SMTP relay (port 25, no auth/no TLS). As a result, outbound email (including workflow notifications and bursting reports) has stopped.
We’re now trying to integrate with a modern SMTP service (SMTP2GO), which requires:
• Authentication (username/password)
• TLS (STARTTLS)
• Non-default ports (2525 / 587)
Questions:

  1. Has anyone successfully configured Workflow Notification Mailer in EBS 12.2 to work with SMTP servers requiring both TLS (STARTTLS) and authentication?
  2. Are there known limitations around TLS 1.2, Java/JDK versions, or JavaMail in this setup?
  3. Is using non-default ports (2525/587) fully supported in practice?
