   The way the 'virtusertable' works is it looks in there for full email 
addresses and when it finds one it checks the associated unix user name 
and sends the email into their spool. So, theoretically (I haven't tried 
this) I suspect that:

user-WNbSnoOWcWBBDgjK7y7TUQ at public.gmane.org	user
user-dL8jOpOjefRBDgjK7y7TUQ at public.gmane.org	user

   *Should* work. That said, I always use different unix users for each 
email address just to keep things separate. Ie: 'user.domain1.com' and 
'user.domain2.com' and then tell the used that their POP3 login name is 
their email address with a '.' instead of an '@' sign. This patch that 
works around this is new to me, so I can't speak to that.

Here are samples of my files:

=- sendmail.mc -=
FEATURE(`allmasquerade')dnl
FEATURE(`masquerade_envelope')dnl

FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable.db')dnl

dnl # Default Mailer setup

MAILER(`local')dnl
MAILER(`smtp')dnl

dnl # Define server and cw file
define(`confDOMAIN_NAME', `mail.alteeve.com')dnl
define(`confCW_FILE', `/etc/mail/local-host-names')dnl

Cw domain1.com mail.domain1.com
Cw domain2.com mail.domain2.com
...
Cw domainN.com mail.domainN.com

user-dL8jOpOjefRBDgjK7y7TUQ at public.gmane.org                user.domain2.com
foo-dL8jOpOjefRBDgjK7y7TUQ at public.gmane.org                 foo.domain2.com
bar-dL8jOpOjefRBDgjK7y7TUQ at public.gmane.org                 bar.domain2.com
@domain2.com                    admin.domain2.com

...

user-8ttO0WTGhi9BDgjK7y7TUQ at public.gmane.org                user.domainN.com
@domainN.com                    admin.domainN.com


   Then once everything is ready run: 'sendmailconfig' (if installed) or 
do whatever you need to do on your server to (re)generate your *.db 
files and to create the sendmail.cf file and restart sendmail.

   I *don't* pretend that these configs are free of typos! I just copied 
from my (working) config files and substituded with fake data to protect 
the innocent. Also, my config may not be optimal... I just know that it 
works. :p
