From James Moe <ji...@sohnen-moe.com.INVALID>
Subject [users@httpd] [OT] bounced messages
Date Mon, 13 Aug 2018 19:43:36 GMT
Hello,
  I received a note from the list manager complaining that our server
has rejected an unconscionable number of message.
  Has there been some configuration change of the mailing list recently?

  There are reasons for the rejections: our SPAM filter.
 1. The filter found one set of messages being sent from a blocklisted
site (23.83.215.44), and rejected the messages.
 2. The filter uses a greylist to decide about the validity if a sender
(nearly 2/3 of spam is rejected this way). The list does not retry
delayed messages?

  This particular site (or IP range) is often blocklisted.
$ host 23.83.215.44
44.215.83.23.in-addr.arpa domain name pointer
crimson.oak.relay.mailchannels.net.
