What's in the aliases, transport and virtual files in
/var/spool/postfix/plesk/?

Well, that's what they used to call the $64000 question. These are all Berkeley Database .db files, which I've never worked with before. If I knew how to read these files (and understand their content, and edit them where necessary) I might be able to solve the whole problem from there.

Apparently this server already has a package called db4-utils installed. I don't know whether these are enough. It's not clear whether there are normal man pages for them.

Also, what's in /etc/postfix/master.cf?

Aside, please see the FAQs at <http://wiki.list.org/x/tIA9> and
<http://wiki.list.org/x/OIDD>.

Yes, I saw these; that's why I wrote in my first post, "I realize this may conceivably be a Postfix issue, or even a Plesk issue, but I thought someone here might be able to guess the answer."

I would most like to find out how to get into those .db files. Failing that, I wonder if it would do any good to delete the site list from the command line and recreate it using Plesk (which seems to produce usable lists on this system). But can this be done safely? Doesn't it say somewhere that Mailman won't run if the site list doesn't exist? (It would have to go out of existence briefly in order to recreate it.)
