I installed mailman3 on a server where mailman21 was installed before. Newly created mailinglists work fine. But if I create mailinglists with a name that was previously used on mailman21 nothing works (same behaviour with and without import of old configs and archives; no logs). I purged all old mailman21 config and data and also old postfix aliases (or at least I do think so).
If I send a mail to old list list1(a)a.b and new list list2(a)a.b I get the following logs
/var/log/mail.log

How can I get more info on why the mail for list1 isn't processed?
Where could old mailman21 or postfix info on list1 be stored that causes mailman3 to not handle the list properly?
How can I diff the config between list1 and list2 from the command line?
