The mailing list for listmasters using Sympa

[Miles Fidelman <address@concealed>]

Folks,

I recently migrated from sendmail to postfix.

Up to now I've been running a single robot, and am now in the process of 
setting up a second - and I find that I'm just a bit confused about how 
postfix handles all the sympa aliases.

Basic setup (which contains some legacy code from my old sendmail setup):

/etc/postfix/virtual.regexp contains
/^(.*)@lists.neighborhood.net$/ lists.neighborhood.net-$1

/etc/aliases contains:
sympa: "| /home/sympa/bin/queue address@concealed"
listmaster: "| /home/sympa/bin/queue address@concealed"
bounce+*: "| /home/sympa/bin/bouncequeue address@concealed"
sympa-request: postmaster
sympa-owner: postmaster

lists.neighborhood.net-sympa:   "|/home/sympa/bin/queue 
address@concealed"
lists.neighborhood.net-listmaster:      "| /home/sympa/bin/queue 
address@concealed

----
my question: when I look at this, I think I understand why 
address@concealed and address@concealed work, 
but I DON'T understand why bounce management seems to work properly

as I read this, the virtual.regexp expression would rewrite any bounce 
messages to
lists.neighborhood.net-bounce....

and there's no alias to feed this to bouncequeue - BUT... bounces seem 
to be working

so... what am I doing right, inadvertently?  And, how do I set things up 
for a new virtual domain so it works properly?

Thanks much,

Miles
