Especially after an upgrade of IDM you might get into a situation where emails stop being sent.
The log file may reveal the following trace:
2013-01-18 11:24:27,954 ERROR [ims.policyxpress.mail] (WorkManager(2)-37)
Failed sending email
However, further down the log trace you see and invalid email address:
Caused by: com.sun.mail.smtp.SMTPSendFailedException: 501 5.1.7 Invalid
The email.properties file that's located under /iam_im.ear/config/com/netegrity/config gets run over by an upgrade. You do need to back it up and restore
it after the upgrade.
That file holds the property of the 'From Address' for your emails. The parameter is: admin.email.address=<Here is where you paste your address>
If that property is left undefined (which is what happens when upgrading without restoring this file) then you'll get into the SMTP exception that is in
the symptom and it will prevent the emails from being sent out.
Make sure to backup this file before the upgrade and restore it to that same location post upgrade and/or me sure to define this value correctly prior to
