No, it's not supposed to work, but I didn't know. I don't have any
mysql tables. The docs say that -s only works with some database
types, but doesnt say which ones, so I suspected it wouldn't work, but
didn't know for sure.

Here's how it looks to me. It was initially set up with email domain
myhost.example.com and that is all fine. It all works as it should.
You then decided that you wanted to be able to post to
listname at example.com so you added a virtual_alias_mapping in
mysql:/etc/postfix/mysql_vam.cf to map listname at example.com to
listname at myhost.example.com where it would be further mapped to local
listname via Mailman's hash:/var/lib/mailman/data/virtual-mailman

The only problem with this is the listname listinfo page, list welcome
messages, etc all say post to listname at myhost.example.com

You can continue to do what you're doing and just change
myhost at example.com to lists.example.com, but that means you have to
manually maintain the particular mappings from listname at example.com to
listname at lists.example.com.

It would be better to just have the email domain as example.com and have

POSTFIX_STYLE_VIRTUAL_DOMAINS = ['example.com']

so mailman creates the virtual-mailman. Then it appears that since
mapping listname at example.com to listname at myhost.example.com in the
current mysql:/etc/postfix/mysql_vam.cf works, you could just remove
those mappings from mysql:/etc/postfix/mysql_vam.cf and let the
mappings in virtual-mailman do the job.

However, read the FAQ  at <http://wiki.list.org/x/ZoCj> which I just
wrote yesterday. Now I'm not sure whether that is even necessary.
Clearly my understanding of Postfix is not complete. In your setup, is
example.com a virtual_mailbox_domain (listed in
mysql:/etc/postfix/mysql_vmd.cf)?
