Lately been having issues with Grey listing, when customers email us from Office 365 takes ages untill its arrives.
So we decieded to start using Grey listing white listing.
let start
Step 1.
let create a file called clients_fqdn_whitelist.local on the sqlgrey listing
Code: Select all
/etc/sqlgrey/clients_fqdn_whitelist.local
let add the domains that will not be added to the sqlgrey listing scan
Code: Select all
Domain.com
domain.net
jamesbond.com
run sudo update_sqlgrey_config after add the domains to the list
Code: Select all
sudo update_sqlgrey_config
this is very important step to get the sql database check the domains. you have to restart the sqlgrey
Code: Select all
sudo systemctl restart sqlgrey
if you have any questions let us know.
