Hi.

I'm looking forward an way to know what lists was used in a specific day.

For example, how to know if any message was sent to
mylist@contact.example.com ?

My lists are announces list only.

I have to write a software to identify if a announce was sent, and
check the Postfix log informations (errors and accepted) with the
members list from Mailman, and, of course, generate a report to list
members that hasn't received the announce because an error and members
that are ok.

No problem with Postfix log files, but I don't know how to verify the
moment that an announce was sent, how many times in a day, which one,
etc.
