LinuxQuestions.org - Postfix +SASL smtp working, but not from ANY ip to ANY address?

Hi all,

I have successfully set up Postfix to do smtp
and use SASL... but at the moment it is just
possible to smtp from IPs i set on mynetworks (e.g. xxx.xxx.xxx.xxx) and ONLY to local addresses.

I want my users to be able to smtp from ANY ip
and send mail to ANY address (even outside my server)

does anyone know how to do this?
(i have wasted ages to make this work.. with no luck)
Below is a small snippet of the relevant configuration
in my main.cf file..

Any help would be appreciated!

Code:

# local

myhostname = mail.xyz.com

mydomain = xyz.com

myorigin = $myhostname

mynetworks = 127.0.0.0/24 xxx.xxx.xxx.xxx

mydestination = $myhostname localhost localhost.$mydomain localhost.localdomain

alias_maps = hash:/etc/aliases

local_recipient_maps = proxy:unix:passwd.byname $alias_maps

local_transport = local





smtpd_recipient_restrictions =

  reject_unknown_sender_domain,

  permit_mynetworks,

  permit_sasl_authenticated,

  reject_unauth_destination,

  reject_rbl_client relays.ordb.org,

  reject_rbl_client sbl.spamhaus.org,

  reject_rbl_client cbl.abuseat.org,



# SMTP AUTH (SASL)

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain = $myhostname

smtpd_sasl_security_options = noanonymous

# Be nice to brokenware like Outlook Express:

broken_sasl_auth_clients = yes
