[Dovecot] proxy_maybe and IPv6

Hi,

Using dovecot 1.1.2 on a dual-stack server, with the 'proxy_maybe' attribute to forward some clients to another server, it seems that only clients connecting with the same protocol version as the one used by address in the 'host' attribute in the password db are recognized as local.

If an IPv4 address is specified as 'host', a dovecot proxy is created for clients connecting using IPv6 to this server, and symmetrically if the proxy is specified as an IPv6 address, clients connecting through IPv4 will get forwarded to the v6 address.

Is there a way to avoid that?
