Hello! I just want to sense the environment about a to be proposed Debian policy change with respect to mail handling.
Maildir delivery has lots of advantages over mbox spools, but the latter is the only standard. Almost all M*A's support both standards. It would be a big relieve, if one could chose either of them at some moment, and this choice would be recorded, let's say in /etc/default/maildelivery The M*A packages could sense this file and configure them accordingly, or refuse to install if they cannot work under the required delivery scheme. Best Regards, Jorge-León
