Hi,

Debian trixie, virtualenv installation: When I entered addresses at the mass subscription field I got:

HTTP Error 400: 'pathlib._local.PosixPath' object does not support the context manager protocol

Compare this post, pretty sure it's the same issue: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/... and see the reply from Mark Sapiro for a patch. I believe this will be fixed in the next release.

Yes, the patch worked. Thanks a lot! Both mass subscription and mail delivery work now!
