I have been googling for a couple hours trying to figure this out. This is happening as we speak on a LIVE mail server, which I thought I had tested properly before rolling LIVE.
What we have is a Postfix server setup with IMAP/POP3, etc. 95% of my users just get delivered locally to postfix. But what I have is 5 users, that need to be forwarded to an exchange server.
The domain is the same for all the users so I can't split by domain.
Noone can send email to these users that are on the exchange system? I keep getting "User unknown in virtual alias table" error messages.
I set up transport maps for the users with smtp: but I can't get the mail to deliver?
Is there some setting somewhere where I can configure that there are extra email addresses that should still be accepted??
Here's my main.cf:
debug_peer_level = 9 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.3.3/samples readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES virtual_alias_maps = hash:/etc/postfix/virtual sender_bcc_maps = hash:/etc/postfix/bcc mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME home_mailbox = Maildir/ smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination myhostname = <hostname> mydomain = <domain> smtpd_banner = Hello. This server uses anti-spam and anti-virus functions. relayhost = <relayserver>:<port> transport_maps = hash:/etc/postfix/transport #fallback_transport = smtp:<ip>:<port> #fallback_transport_maps = hash:/etc/postfix/fallback_map luser_relay = dcmoody@<domain>
I've tried adding the email addresses to the virtual file pointing to themselves and that didn't work.
