I'm trying to allow-list (formerly whitelist) a TLD. I have these lines in my postfix main.cf:
check_client_access hash:/etc/postfix/client_checks, check_sender_access hash:/etc/postfix/sender_checks, check_client_access hash:/etc/postfix/rbl_override, For the rbl_override file is siriusxm.com sufficient? Or do I need e.siriusxm.com or even r193.e.siriusxm.com? Maillog message is: Apr 29 17:20:46 lazygranch postfix/smtpd[10668]: NOQUEUE: reject: RCPT from r193.e.siriusxm.com[192.243.230.193]: 554 5.7.1 Service unavailable; Client host [192.243.230.193] blocked using zen.spamhaus.org; from=<bou...@e.siriusxm.com> to=<li...@lazygranch.com> proto=ESMTP helo=<r193.e.siriusxm.com> For your entertainment, customer support at SiriusXM is having all sorts of problems with email bouncing. Like maybe someone there could, you know, check the log for bounces? They said to use a gmail account. I assume they don't bounce spam but put it in a spam folder.
