Thanks Kevin, 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 -Max From: Kevin A.

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.
