Thanks for your quick reply, Mark.

I see, I've retried without the -l switch and the shell returns without error.

The --help switch returns:

# mailman shell --help usage: mailman shell [-h] [-i] [-r RUN] [--details] [LISTNAME]

positional arguments: LISTNAME The 'fully qualified list name', i.e. the posting address of the mailing list to inject the message into. This can be a Python regular expression, in which case all mailing lists whose posting address matches will be processed. To use a regular expression, LISTNAME must start with a ^ (and the matching is done with re.match(). LISTNAME cannot be a regular expression unless --run is given.

Thanks once again, Simon.

Hi everyone,

I'm sorry to resurrect this thread from so long ago but it appeared to provide exactly the answer I was looking for, trying to manage pass_types in 3.1.1 on Ubuntu 18.04.

GNU Mailman 3.1.1 (Between The Wheels)

Unfortunately when I run:

./bin/mailman shell -l [list address]

I receive:

usage: mailman [-h] [-v] [-C CONFIG] {help,aliases,conf,create,digests,import21,info,inject,lists,members,qfile,remove,reopen,restart,shell,start,status,stop,unshunt,version,withlist} ... mailman: error: unrecognized arguments: -l

Can anyone advise how I can use the -l switch to manage this setting for a list?

Older versions of Mailman core did not support the -l/--listspec option for mailman shell. They expected the listname as an argument as in

mailman shell list@example.com

What does

mailman shell --help

show in your case?
