hi

i'm currently in the process of setting up a mailserver with multiple
virtual domains and there are currently 2 problems:
1) if i try to send a mail to any one of the virtual alias users i get an
"User unknown in virtual alias table" error
2) the mail is bounced instead of being rejected at smtp time

the system is a debian etch server with postfix debian package version
2.3.8-2+b1.

as for the first problem:
the strange thing is that i can look up the user in /etc/postfix/virtual
with "postmap -s" and "postmap -q user1" without a
problem and get back the correct unix account, so in my opinion it
should work(?)...

for the second problem:
as you can see in the postconf -n output below, local_recipient_maps is
set to what for me looks like to be correct...

postconf -n output (the domains are real ones actually, inet_interfaces
= localhost is for testing because of the bounce problem):

most likely it's something trivial that i haven't thought about :)

thx for any advice
