Hi,
postfix-2.2.10-1.2.1.el4_7 Red Hat Enterprise Linux AS release 4 (Nahant Update 5) 2.6.9-42.ELsmp postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 html_directory = no inet_interfaces = localhost mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.2.10/README_FILES relayhost = [a.b.c.d] sample_directory = /usr/share/doc/postfix-2.2.10/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_generic_maps = hash:/etc/postfix/generic unknown_local_recipient_reject_code = 550 I have setup smtp_generic_maps on the postfix server, it simply relays through a.b.c.d however this relay will only accept mail from a specific domain (call it xyz.com). Here is my smtp_generic_maps r...@host.domain root-dom...@xyz.com However I am still not receiving emails. I have set this up the same on a different system and it works as expected. I can see that on the successful system postfix relays via 127.0.0.1 first from maillog, but on the unsuccessful system postfix relays directly via the relayhost. This makes me think it's possible that because the failing system is relaying directly via the relayhost (well at least theres not mention of localhost in maillog) that the address masquerading is not taking place. I do not have access to the next relay server to check the logs unfortunately. Can anyone see anything particularly dumb that I'm doing here please ? Thanks Nick.
