Yeah not trying to welcome them entirely, more so like other well-known domains
that are commonly seen and will not be blacklisted (e.g. docs.google.com ).
I will try out:
uridnsbl_skip_domain ct.sendgrid.net
Tell me please if it works, I'm afraid it won't exactly because of the
util_rb_3tld ct.sendgrid.net
which seems to cause not finding ct.sendgrid.net in lists of domains to
skip:

if it doesn't work, I guess you could use something like:
dns_query_restriction deny ct.sendgrid.net.multi.uribl.com
ct.sendgrid.net.multi.surbl.org ct.sendgrid.net.spamhaus.org
ct.sendgrid.net.lookup.dkimwl.org

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.
