Hi,

Please let me know where I can post my question if this list is not the right place.

I'm configuring a mailing list server, migrating from Mailman 2.1 to 3.2.2, and I can't get the migrated mailing lists to work. When I create new mailing lists there is no problem.

Here are the versions of Mailman I run :

mailman 3.2.2 mailman-hyperkitty (1.1.0) django-mailman3 (1.2.0) postorius (1.3.2) mailmanclient (3.2.2) HyperKitty (1.2.2)

The command line I use the migrate the mailing list:

/opt/mailman_venv/bin/mailman -C /opt/mailman_venv/var/etc/mailman.cfg import21 mltest@test.domain /var/vmail/mig/data/lists/mltest/config.pck

When I send an email to a migrated list, of which I made myself a member, no mail is sent, and I get the following stack trace in the log:

==> /var/log/mailman/mailman.log <== Jan 21 15:02:37 2020 (15948) Uncaught runner exception: None Jan 21 15:02:37 2020 (15948) Traceback (most recent call last): File "/opt/mailman_venv/lib64/python3.6/site-packages/mailman/core/runner.py", line 173, in _one_iteration self._process_one_file(msg, msgdata) File "/opt/mailman_venv/lib64/python3.6/site-packages/mailman/core/runner.py", line 266, in _process_one_file keepqueued = self._dispose(mlist, msg, msgdata) File "/opt/mailman_venv/lib64/python3.6/site-packages/mailman/runners/incoming.py", line 79, in _dispose process(mlist, msg, msgdata, start_chain) File "/opt/mailman_venv/lib64/python3.6/site-packages/mailman/core/chains.py", line 40, in process chain = config.chains[start_chain] KeyError: None Jan 21 15:02:37 2020 (15948) SHUNTING: 1579615357.5331464+c5918e305ec281d47ef0caaed070c8c4bde26ee3

It seems like the start_chain has value 'None' and that prevents the mail from processed, but I can't find where to correctly set the start_chain.

Please let me know how I can remedy this issue.
