Looking to check if my understanding is correct or there is some sort
of bug.
I have the following entry in my local.cf file:
util_rb_3tld ct.sendgrid.net
I would expect that ‘ *.ct.sendgrid.net ‘ would be excluded from any
URI BL lookups?
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
