Hi, I'd like to obscure the names of the DNSBLs that we use in response to emails that are rejected. I've set up postscreen_dnsbl_reply_map and it's working properly for most:
Oct 20 21:41:36 mail02 postfix/postscreen[17651]: NOQUEUE: reject: RCPT from [46.102.117.88]:43226: 550 5.7.1 Service unavailable; client [46.102.117.88] blocked using multiple DNS-based blocklists; from=<p...@brimsems.com>, to=<g...@example.com>, proto=ESMTP, helo=<scaffold.brimsems.com> However, there are others where it doesn't seem to apply. Perhaps because of the '554 5.7.1' response compared with the '550 5.7.1' from above?

Thanks, Alex
