May I suggest Postfix and Mailman logs. Starting some time before, and ending some time after an "outage". That would show something about cause and effect. For example: - Postfix received no mail for Mailman. - Postfix received mail for Mailman, but could not deliver it to Mailman. - Postfix delivered mail to Mailman, but Mailman could not send mail to Postfix. - Postfix received mail from Mailman, but could not deliver it to the Internet.
