Hello!

I have the same problem:

1. I need to permit some internal users (not all) to send mail to any

external user (Internet)

2. I need to permite any external user to send mail to some my internal

users (not all)

In fact, the problem is: just "some" of my internal users have permission to

receive mail from and send mail to the Internet.

How can I solve this?

In the example below, the same list of restricted_users is used for

controlling both who can send and who can receive internet mail. If you

don't require the local_plus feature, just leave that part out.

1. in main.cf:

1. use restriction classes to make restricted_users file more readable.

   smtpd_restriction_classes = local_only, local_plus

local_only =

reject_unauth_destination

permit_mynetworks

reject

local_plus =

check_recipient_access hash:/etc/postfix/local_plus

check_sender_access hash:/etc/postfix/local_plus

reject_unauth_destination

permit_mynetworks

reject

1. this is the default setting, required for this setup.

   smtpd_delay_reject = yes

1. we'll do this in sender restrictions to avoid open relay problems.

   smtpd_sender_restrictions =

   check_sender_access hash:/etc/postfix/restricted_users

   check_recipient_access hash:/etc/postfix/restricted_users

and in /etc/postfix/restricted_users

# /etc/postfix/restricted_users

# this file contains a list of users only allowed to send and receive local

mail

# postmap this file after changes

# local users not listed here have no restrictions

[email?protected] local_only

[email?protected] local_plus

and in /etc/postfix/local_plus:

# /etc/postfix/local_plus

# this file contains allowed destinations and senders

# for users restricted to local_plus

# postmap this file after changes

miproveedor.com OK

Remember to "postmap local_plus" and "postmap restricted_users" after

making changes to them.

Remember to run "postfix reload" after changing main.cf
