Dear Experts,
I have an Oracle APEX on the Cloud (ATP).
I have also initiated another virtual linux machine. Installed Sendmail on the linux machine..
If i try to use the Sendemail.. i am able to send the mail from the Linux machine.
I want to use this SMTP server details for the APEX instance
tried the below
BEGIN
APEX_INSTANCE_ADMIN.SET_PARAMETER('SMTP_HOST_ADDRESS', '
xxxxxx.subnet.vcn.oraclevcn.com');
APEX_INSTANCE_ADMIN.SET_PARAMETER('SMTP_HOST_ADDRESS', '25');
COMMIT;
END;
The mail queue still throws an error "ORA-29278: SMTP transient error: 421 Service not available"
I also created an open ACL so the connectivity is not blocked
Any clue of how to solve this ?
TIA
Bala
