[Mailman-Users] Mailman post not sent to email address in same domain

Bradley Cummins, Member Manager writes:

You'll see in the two postings below which were taken from the smtp log that a member was dropped in the second posting. I also looked through the maillog, and found the same result there. One email address was left off of the list serve recipients.

Any ideas?

The email address which was dropped may have been the poster or an explicit recipient, with the appropriate "no dupes, please" flag set. There are two of these; 'not metoo' says "don't send to me when I am the poster," 'nodupes' "don't send to the post to me if I am in To or Cc."
