Fix email sending authentication issue

[emranbm]

There is a celery task that emails timesheets periodically. Currently, it fails due to the change to the mail server authentication system. It may or may not be fixed by replacing the new credentials.
The error log:

The issue was just about a recent password change. It fixed after password cariable update...
