Myself Ninad and we are using mailman 2.1.29 from long time. From last few days, I have observed a strange behavior in mailman. mailman not sending email to all the members of mailing list and the mail is getting posted to random members of the list.

Even "nomail" option is also not set for the members. I observed this issue with random mailing lists. Below are the some logs form the smtp log. I dont know how can I debug this issue. I kindly request all to guide me in this regard.

I can't tell much from the log entries (some notes below). The reasons why a regular (non-digest) member might not be sent a specific post include in addition to "nomail" include: option is set.

• member is explicitly addressed in To: or Cc: and member's nodupes

• member is the sender of the post and member's mot metoo option is set.
• list has topics defined and enabled and the user is subscribed to one or more topics and either the message matches a topic the user is not subscribed to or the message matches no topics and the user's ReceiveNonmatchingTopics option is No
• the list defines regular_exclude_lists and the user is a member of one of the excluded lists.

In addition, a user may not receive a post that Mailman sends because it bounces or the user's ISP files it as spam or silently discards it. You need to look at the outgoing MTA logs to see if the message was sent.

This post sent to only 10 recips, probably because one was directly addressed.

The others have 62 or 63 recips, The one missing in the 62 cases is probably directly addressed.
