I am facing some issues with sending email from DBCS using UTL_SMTP
My package is as below:
create or replace PROCEDURE send_mail (p_to IN VARCHAR2,
p_from IN VARCHAR2,
p_message IN VARCHAR2,
p_smtp_host IN VARCHAR2,
p_smtp_port IN NUMBER DEFAULT 25)
l_mail_conn := UTL_SMTP.open_connection(p_smtp_host, p_smtp_port);
UTL_SMTP.data(l_mail_conn, p_message || UTL_TCP.crlf || UTL_TCP.crlf);
'Test Message from SMTP - UAT 4',
SMTP and ACL is configured on the Database.
When I call this procedure, I get the email, but it is inconsistent.
If I make the same procedure call 10 times, for example, I get email 5-6 times.
The remaining 4 times I don't get any email.
This is causing issues for me in many UAT code packages as emails are not sent consistently.
Can you please advise what I need to check.
Doesn't seem to be a code issue to me as I do get emails a few times.
Thanks in advance for your time.
It's possible that there's an issue with the network and/or the email server. Or the mail server may have rules in place to throttle traffic if it gets lots of messages with the same from/to addresses.
So work with your network and email server admins to see if the requests are making it to the mail server.
If the mails aren't making it to the mail server, add logging to your code to verify all the steps are working.
