On the installations with the Billing Application node running RHEL/CentOS 7, the To (and in some cases From) field of a notification message may remain empty and as a result, the message will not be sent.
To fix such issue, do the following:
Review the failed emails:
Login to Billing Provider Control Panel and go to System > Logs > Outgoing E-Mail Log.
Find the emails with empty "To" and "From" fields with the "Error" status.
- Delete those that are irrelevant.
Install the updated rpm with a fix for this issue:
Log in to the Billing Application node via ssh as root and run the following commands:
# yum clean all # yum update libetpan
Ensure that the necessary package was updated. Run the following command for this purpose:
# yum list intalled libetpan.x86_64
which should print the following to display:
Installed Packages libetpan.x86_64 1.6-2.el7.centos
mind the version of the package: it must be 1.6-2 or greater.
Restart the billing service via the following command:
# service pba restart
- Resend the remaining notifications manually.
