So mail-server.mydomain.my is in mydestination and is thus a postfix
local domain, yet it seems to use the dovecot LDA rather than Postfix
local delivery.

But here, $mydestination is a relay domain so possibly
relay_recipient_maps is overriding transport_maps and that is why list
addresses are relayed to dovecot rather than local

Better to uncomment the above
but it doesn't affect this issue.

This all looks good except the Postfix things I noted above. The
hash:/etc/mailman/transport-mailman entry in transport_maps should
specify the 'local' transport for the list addresses, but somehow this
is overriden, possibly by relay_recipient_maps, and the dovecot LDA is
used for these addresses. This is why it doesn't work. Exactly what to
do to fix it is beyond my Postfix expertise. It seems to me that
transport_maps should take priority in defining the transport used for
a matching address.

Have you redefined the 'local' transport in master.cf to use dovecot?
If so, this can't work with Mailman. If so, you could define another
transport, say 'reallylocal' to use postfix local delivery, and modify
the sed command in /etc/mailman/virtual_to_transport to specify that
