I completed the settings to send mail from APEX.
However, when sending an email, the message 'Success' appears, but there is no response.
The mail send count does not increase, and an error message does not occur.
Can you help me with what I should check?
1. First, I registered the information of the mail and wallet tabs in the internal instance. The smtp server I use requires SSL authentication.
2. ACL registered in DB.
begin
dbms_network_acl_admin.append_host_ace(
host => 'mail.nlcbiz.co.kr',
lower_port => 465,
ace => xs$ace_type( privilege_list => xs$name_list('connect'),
principal_name => 'APEX_230200',
principal_type => xs_acl.ptype_db));
end;
3. A wallet was also created.
mkstore -wrl /home/oracle/wallets -create
4. After completing all the setup and performing many tests, the problem was not solved. However, the part I don't understand is that when executing validation of the server settings, the following results appear.
I doubt this error is causing the problem, but I haven't found any workarounds or references for the error.
I showed all my work. However, it is difficult to understand why this error occurs, and it is difficult to find a reference for this error.
Do you happen to know how to solve this problem?
