Symptoms

Email notifications for approval workflows are not coming through for certain users and tasks intermittently.  The same notifications are missing from Fusion Applications and BPM worklist. They are available on the Bell Notifications but the approvers in question  do not intend to log in to the application. They rely on email notifications only .

Users expect email notifications for all tasks.

 
The issue can be reproduced at will with the following steps:

The gateway email infrastructure team response:

Administrators checked the VM and found email sent to relay:
[root@<host> <pod>:ADMIN-APPS ~]# grep "<email_address>" /var/log/maillog
Feb 11 20:49:30 <host> sendmail[9999]: abcdefghij: to=<email_address>, delay=<delay>, xdelay=<xdelay>, mailer=relay, pri=<pri>, relay=<host.domain>. [ip_address], dsn=<dsn>, stat=Service unavailable
Receiving User: <email_address>

In this case Oracle refused to relay the email. It is likely that this is due to the size of the email. Oracle limits emails to a total size (data, headers & attachments) to 15MB . Since the VM attempted to relay but the mail server refused this is the most probable explanation. There will be no logs on the relay for this as the relay refused the connection.
