Heh... I'm more than a little confused right now, so no worries.

But see below - I actually think I've at least answered how/why it is
working, but I'm not sure what needs to be done to 'fix it' - or even if
it needs 'fixing'...

No :( is it supposed to?

# postmap -s mysql:/etc/postfix/mysql_vmm.cf
postmap: fatal: mysql table /etc/postfix/mysql_vmm.cf: sequence
operation is not supported

Now... toward the end of your email, you had essentially summed up the
issue as:

So, I started at the beginning and started querying all of my maps, and

# postmap -q listname at example.com mysql:/etc/postfix/mysql_vam.cf
listname at myhost.example.com

which then maps to

# postmap -q listname at myhost.example.com

and /var/lib/mailman/data/virtual-mailman is fully populated with these
STANZA's for all lists:

# STANZA START: listname
# CREATED: Wed Jan 11 18:32:22 2006
listname at myhost.example.com              listname

But this kind of seems backwards to me... or at least, more complicated
than it needs to be. Maybe I initially wanted a virtual setup, but now
realize I only need lists for the one/main domain? <shrug>

Anyway, now I guess I just need to know if there's anything broken that
I really need to fix, or at least if it can be simplified. I'm also
thinking long term, for when MM3 is released and upgrade time comes.

Thanks again Mark...
