Users do not receive any automated emails from the SMTP server even when SSPR is configured to send emails. You receive the error Unable to send Email: No From Address. This message is displayed only when SSPR is installed on a SLES machine and the machine name is not defined in the host file.
To resolve this issue, perform the following:
On the SLES server where SSPR is installed, include the machine name in the host file of the etc folder. You require to replace 127.0.0.1 localhost with 127.0.0.1 <name of the machine> localhost.
