Hi,

according to http://wiki.dovecot.fi/PasswordDatabase/ExtraFields/AllowNets

there exists an option allow_nets to restrict IP ranges from where users are allowed to login to Dovecot.

I am using Debian Etch with the official Dovecot packages: # dpkg -l | grep dovecot ii dovecot-common 1.0.rc15-2 ii dovecot-imapd 1.0.rc15-2 ii dovecot-pop3d 1.0.rc15-2

using a mostly unchanged dovecot.conf.

I tried to add the line

allow_nets=127.0.0.0/8,192.168.0.0/16

in the block

passdb pam {

which is the default enabled auth code in Debian.

When starting Dovecot I get this error message:

# /etc/init.d/dovecot start Starting mail server: dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 777: Unknown setting: allow_nets

According to the Dovecot changelog

2006-02-27 18:46 Timo Sirainen timo.sirainen@movial.fi

• src/auth/: auth-request.c, auth-request.h: Added "allow_nets" extra field. If set, the user can log in only from within the given networks (hope the code is correct...)

the option exists since February 2006, while the Debian package was released in December 2006.

What I am doing wrong?

Using TCP wrappers instead seems not to be an option according to http://dovecot.org/list/dovecot/2006-April/012476.html
