[Dovecot] allow_nets and deliver + userdb lookup

[Pavel Volkovitskiy]

Hello!

I'm trying to restrict imap logins to our internal network for several 
users, but this breaks dovecot delivery too

Even if i set allow_nets to NULL or 0.0.0.0/0 deliver exits with "Error: 
Auth lookup returned failure"

i'm running it as 'command = /usr/lib/dovecot/deliver -e -d 
"$local_part@$domain" -s' in exim.conf

i guess delivery lookups should be independent  of allow_nets

i'm  using dovecot 1.1.13 + managesieve patch
