: I get the same thing, after nearly every email I send directly to the : lucene/solr lists (as opposed to auto-sent JIRA posts).
FWIW: I've never seen this, so i suspect it has something to do with the mail properties -- probably a SPAM filter that lies to you about why it's rejecting your mail. Since we've not received multiple reports about this particular domain/address, i'll reach out to the subscriber and see if we can resolve hte issue one way or another. : I don't think it delays my messages though. Correct -- this domain is not afiliated with apache in any way (that i know of) and would be well downstream of hte mailing list software. it bouncing a message would have nothing to do with how long it takes any other subscriber to recieve the message. -Hoss
