this is a nice feature and active here since 2011-01 but be careful if you use postfix behind a barracuda-spamfirewall the firewall has to be exlcuded from "smtpd_reject_footer" because it will answer only the last line (reject footer) to a sending server if the rcpt does not exist and the sender does not get "User unknown" main.cf: barracuda_smtpd_recipient_restrictions = permit_mynetworks, reject master.cf: 10.0.0.15:10026 inet n - n - - smtpd -o mynetworks=10.0.0.20 -o smtpd_client_connection_count_limit=75 -o smtpd_recipient_restrictions=$barracuda_smtpd_recipient_restrictions -o receive_override_options=no_header_body_checks,no_milters -o local_header_rewrite_clients= -o sender_dependent_relayhost_maps= -o content_filter= -o smtpd_delay_reject=no -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_helo_required=no -o smtpd_sender_restrictions= -o smtpd_sender_login_maps= -o smtpd_data_restrictions= -o smtpd_end_of_data_restrictions= -o smtpd_restriction_classes= -o smtpd_error_sleep_time=0 -o smtpd_soft_error_limit=1001 -o smtpd_hard_error_limit=1000 -o smtpd_client_connection_rate_limit=0 -o smtpd_peername_lookup=no -o smtpd_use_tls=no -o smtpd_tls_security_level=none -o smtpd_sasl_auth_enable=no -o smtpd_reject_footer= -o max_idle=1h -o max_use=1000
