Hi, New user here. It appears since Jan 31 20:52:44 Australian Eastern DST a number of SMTP servers *all* running cPanel started to reject with SMTP 550 SMTP connections from at least: 175.45.x.x/16 172.105.177.207 14.201.136.92 45.79.35.45 I'm not a cPanel user and the question is: How can we find out what are the preconfigured RBLs in a default cPanel installation? My guess is one of those RBLS has started to block accidentally some IP addresses / net blocks in the last 24 hours or so. None of the above IPs are coming up as blacklisted with

  Hey there! In case you haven't seen the issue yet, SpamCop had their domain expire leading to problems with their RBL and many mailing systems:

  @burnleyvic - we seem to already do that in the mail logs. I checked my personal system for "RBL" in the /var/log/exim_mainlog file and I found this entry: 2021-01-31 05:03:31 H=(remote.spammer.server) [1.2.3.4]:58726 F= rejected RCPT : "JunkMail rejected - (server.spammer.com) [1.2.3.4]:58726 is in an RBL: Blocked - see https://www.spamcop.net/bl.shtml?1.2.3.4"
  Are you expecting to see that in a different location on the machine?
