I have three list admins each maintaining one list, thus three lists: E, H and S. All reports that some mails they release from Held messages are sent, some isn't.

In the logs (Mailman smtp.log and postfix log I can confirm that at least one of the lists (E) sent out another message to 559 recips at Sep 26 09:31:12 201 (UTC+2) so something is working.

The admin of list E explains that she have released mails that came out, but some mails isn't sent when she reases them. Among others a mail she released Sep 26 09:38.

I can also see in the Mailman Postfix log that Mailman received a mail from the Admin's e-mail address sender@foo.bar.

I cannot find the mail-id in the Mailman smtp.log, however in the smtp.log I found that the mail was received

I don't see any release of the held mail not that it was sent out. Two hours later I see a a log message about a notification mail to the admin that another mail had been held, but not anything about the released mail neither in thge smtp.log nor the postfix log.

I don't know why it only works sometimes.
