Just under the "conn = ..." line, insert

to enable debugging. Save the file, and send a message to the problematic list. Debugging output (i.e. a transcript of the entire SMTP dialogue) should now be in ~mailman/logs/error. Remember to remove the debugging line again afterwards.

Ok, I put that in there, and debugging shows up in other places, but not in that error log.

OK, so I might have guessed wrong about the location of the resulting log file :)

Anyway, I had changed one of the user's settings to digest, so he would at least get the list messages. Then when I was going to do the above test, I changed him back to regular to see what happened, when he showed up in the recipient list. I did the same for another user that was being ignored, (change to digest and back to regular) and now he is getting mail too. I don't know what was going on there, but it appeared to be reproducible. Earlier, I had removed and re-added them to the list, but that did nothing.

Odd -- Internally, changing to digest only moves the address from the members' dict to thedigest_members' dict, and reversing the change reverses the move.

Thanks for the help, Harald. I don't think that was a solution, but I appreciate your efforts.

If this really is unrelated to your MTA, then the output of the following commands might prove helpful in debugging (should you encounter the problem again):

$ cd ~mailman $ python Python 1.5.1 (#1, Oct 9 1998, 15:23:54) [C] on sunos5 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam

from Mailman import MailList import pprint list = MailList.MailList("PROBLEM_LIST_NAME", lock=0) pprint.pprint(list.__dict__)

Substitute the name of the problematic list name for PROBLEM_LIST_NAME.
