We might sometimes forget the password for the email accounts on the server.
We can easily find out the email accounts and their passwords existing on the server with the following command:
/usr/local/psa/admin/bin/mail_auth_view
This command will show all the email accounts on the server along with their passwords.
Use following command to calculate total amount of email accounts on the server:
/usr/local/psa/admin/bin/mail_auth_view | wc -l
Done!
