Hi all,

we currently have a problem sending to an email list. The mailing list is an announcement list and is therefore moderated. The mail also arrives for moderation. However, when the mail is released, it is not delivered, but moved to the shunt queue. The error after an unshunt attempt in the log:

Any hints how we can solve the problem here?

One of the list's regular members has no associated address record. I don't know how this can happen.

You could find the member with mailman shell, e.g.

mailman shell -l list.example.com
Welcome to the GNU Mailman shell
Use commit() to commit changes.
Use abort() to discard changes since the last commit.
Exit with ctrl+D does an implicit commit() but exit() does not.
The variable 'm' is the list.example.com mailing list
 >>> for mbr in m.regular_members.members:
...     if mbr.address is None:
...         mbr.subscriber
...         mbr.user
...         mbr.user.addresses
...         mbr.user.preferred_address
...

You might be able to fix this with something like

 >>> for mbr in m.regular_members.members:
...     if mbr.address is None:
...         mbr.address = mbr.user.preferred_address or 
member.user.addresses[0]
...
 >>> commit()
