Problem while intergrating OCI (DRCC) with external SMTP
in Database
Summary: I need assistance in configuring SMTP for sending emails via Oracle APEX 24.2 on our Oracle 23ai Autonomous Database (ADB).
I have followed the documentation provided online, but the emails remain queued in APEX_MAIL_QUEUE with MAIL_SEND_COUNT = 0 and MAIL_SEND_ERROR as NULL. No emails are being delivered.
Below is a summary of our current configuration and validations performed:
Configuration Details:
- SMTP_HOST_ADDRESS: OUR_HOST
- SMTP_PORT: 587
- TLS Mode: Tried both enabled and disabled
- SMTP_AUTHENTICATION: Enabled
- Email Sending: APEX_MAIL.SEND successfully queues messages
- Queue Status: Messages remain in APEX_MAIL_QUEUE without errors
- NSG/ACL:
