[Web-cyradm] problem with proxy on postfix

[martynas at inet.lt]

Hello,

I use proxymap/proxy with postfix. There is a problem, that proxy dont work
with "mydestination". Others tried to setup:

mydestination = localhost $myhostname
virtual_alias_domains = proxy:mysql:/etc/postfix/mysql-mydestination.cf
virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual.cf

And reported, that it works.
But when I setup like this, I get error:

Mar 30 21:04:21 srv2 postfix/error[26090]: 3723B52DAB: to=<vejas at domain.lt>,
relay=none, delay=0, status=bounced (user unknown in virtual alias table)

I use systems, where username = email (usernames with "@"). I get the same
errors on 2 systems:
1. cyrus-imapd 2.1.13(+patch, that allows username = email) + postfix 2.0.10
2. cyrus-imapd 2.2.3 (username = email) + postfix 2.0.14

So, any ideas would be appreciated..

regards,
