is rumored to have said:

It sounds like you still have a working postfix+dovecot setup. :-)

Yes, I suppose so!  But I keep poking at it so much, I worry :)

Indeed I wouldn't expect dovecot to know any such user, so I'm not
sure what step I've missed...

In my postfix main.cf I have:

Unfortunately, you've left out the critical information: dovecot
routing.  Clearly, dovecot has a relatively high-priority routing for
local traffic, and it's sucking up everything addressed to your host
before Mailman gets a whack at it.  There are several possibilities,
so it doesn't make sense for me to guess.

Hmm, the dovecot-related settings in main.cf seem to be:

```
mailbox_transport = lmtp:unix:private/dovecot-lmtp
smtpd_sasl_auth_enable = yes
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_local_domain=$myhostname
smtpd_sender_login_maps = hash:/usr/local/etc/postfix/smtpd_sender_login_maps.txt
virtual_transport = lmtp:unix:private/dovecot-smtp
```
Do those give a clue?

virtual_transport definitely looks wrong, but I can't tell you what it should be without full 'postconf -Mf' and 'postconf -nf' output and maybe more details about why you have a "dovecot-smtp" transport defined using lmtp at all.

E.g. On all my Mailman boxes with postfix "virtual_transport = virtual" but that's also the default, so presumably you've done something different.
