You are mixing two different methods of delivering mail to Mailman. You
want to use either aliases and virtual alias maps or
postfix_to_mailman.py. These are separate methods and are not
compatible with each other.

Aliases/virtual maps are appropriate in all cases and can generally be
automated with settings such as you have above in mm_cfg.py, however,
you are missing a reference to
hash:/var/lib/mailman/data/virtual-mailman in virtual_alias_maps in
main.cf.

On the other hand, to use postfix_to_mailman.py which works well only
if you have a dedicated domain for Mailman lists with no non-list
addresses, you put "MTA = None" in mm_cfg.py and remove all the other
Postfix stuff from mm_cfg.py. You also need something in
transport_maps in Postfix to tell Postfix to use the 'mailman'
transport for all mail to the 'list.mydomain.com' (or
'list.infoservices.in') domain. See the comments at the beginning of
postfix_to_mailman.py for additional configuration information.

Note that postfix_to_mailman.py is a third party module officially
unsupported by the GNU Mailman project. If you want to use it, you
should go to whatever entity suggested it to you for support.

No. Mailman list addresses should never by local accounts/mailboxes.
