Hi there,

        I've come across a problem when building my new mail relay. My new
mail server is supposed to accept mail for all domains which we virus check
e-mail for and also from certain clients who pay to have outgoing e-mail
swept for viruses. The actually virus checking is handled by the machine
set as 'relayhost' in main.cf.

        I have the following config lines in main.cf:

##########
relay_domains = $mydestination, /etc/postfix-in/relays

smtpd_recipient_restrictions =
        permit_mynetworks
        check_client_access hash:/etc/postfix-in/client_access
        check_relay_domains

smtpd_client_restrictions =
        permit_mynetworks
        check_client_access hash:/etc/postfix-in/client_access
        reject
##########

        When I connect to the mail server from a client listed in
/etc/postfix-in/client_access I can send mail to any domain. This is good.

        Connecting from a client NOT listed in /etc/postfix-in/client_access
should allow me to only send mail to domains listed in
/etc/postfix-in/relays. However, I cannot. I get the error message:

                554 <host[IP]>: Client host rejected: Access denied

in the logs. This is bad.

        I thought that this may be to do with the ordering of
'check_client_access' and 'check_relay_domains' in the config file, but
swapping them around broke the system even more.

        Advice? Comments?

        Thanks,
