[Mailman-Developers] More about bug creating lists in 2.1a3+

Looking at the lists directory the new lists are there. However I can't delete them, (i get a similar bug message) and posts sent are bounced back with a 'user unknown' (the listname) mesage.

After running genaliases, messages to new lists are not bounced but, postfix log says 'fatal: open database ...aliases.db: Invalid argument'

It seems that there is no problem however with old lists created before the update.

Any ideas?

TIA, JA.
