Hi Max, sorry, no.  That command makes it so that RBL lookups treat that 
as a 3rd level domain.  For example, say I have the domain 
somerandomexample.co.uk in my email.  Without a setting that ".co.uk" is 
a 2TLD, then the look for the rbl is wrong.  So say you had 
xyz.ct.sendgrid.net and you want to list it on an RBL but not list 
pdq.ct.sendgrid.net, you would set ct.sendgrid.net as a 3TLD and then 
you can list the xyz or pdk individually.

To skip RBL lookups, you will likely want a welcomelist entry to/from if 
you receive or send emails with the domain in question [1] and to look 
at the config/user pref uridnsbl_skip_domain.

Regards,

KAM
