How to bypass greylist in ESVA?

I found that a lot of people looking for a way to disable greylist in ESVA.

Here is a workaround to handle greylist setting.

1. Login into ESVA console.

2. Edit file /etc/sqlgrey/clients_fqdn_whitelist.local

3. Add *.* to this file. Save it.

4. service sqlgrey restart

I tried this setting in ESVA 1.7 and ESVA2
