cPanel: SMTP error 535 Incorrect authentication data

Sometimes when sending emails on the website through SMTP scripts and Contact forms the following error is observed

535 Incorrect authentication data

To fix this

 

1. Login to WHM with root credentials and navigate to

Home » Security Center » SMTP Restrictions

 

2. If SMTP Restrictions is enabled, just disable it

cpanel_smtp_restrictions

 

3. Now try sending the mail again, this time it should work.
