Smtp autenticado quando tem relay autenticado

Pessoal

Tenho um servidor de email interno com postfix, clamav, spamassassin, procmail , fetchmail sem mysql que para enviar as mensagens para internet usa o servidor do provedor usando a opçao relayhost com senha em um arquivo separado.
O problema que estou enfrentando é que os usuarios internos para poder enviar mensagem deveriam se autenticar no servidor interno e este usar o relayhost para enviar.
Deste modo existe uma confusao entre smtp autenticado e relay autenticado que nao consigo resolver.
A configuracao é a seguinte:
main.cf
-------
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
append_dot_mydomain = no
home_mailbox = MailDir/
mailbox_command = /usr/bin/procmail

myhostname = postfix.net.br
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases

relayhost = smtp.provedor.com.br

smtp_sasl_password_maps = hash:/etc/postfix/saslpass
smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated
header_checks = regexp:/etc/postfix/filtro-cabecalho
debug_peer_level = 9
debug_peer_list = 192.168.1.1/24
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtpd_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom

O que pode estar errado??

Caro,

Porque você não solicita para seu provedor, liberar seu IP no Relay?

Falou,

William

O relay autenticado esta funcionando perfeitamente.
O problema é que quero evitar usuarios internos usarem o servidor interno sem se autenticar mantendo o relay autenticado do jeito que esta hoje.

Ninguem pode me ajudar??
Como uso relay autenticado sera que o unico modo é colocar os usuarios/senhas internos no mesmo arquivo do usuario/senha para relay?
smtp_sasl_password_maps = hash:/etc/postfix/saslpass

No aguardo.
