I'm trying to set up postfix to relay mail using virtual_alias maps but they are getting bounced. I've already checked to make sure the domains are in my virtual_alias_domains table but everything seems to be set correctly. How can I diagnose this issue? Below is information that might be of help: Code: Aug 2 00:07:01 server2 postfix/smtpd[6729]: NOQUEUE: reject: RCPT from <sender address>: 454 4.7.1 <recipient address>: Relay access denied; from=<sender address> to=<recipient address> proto=ESMTP helo=<sender server> Code: # postconf -n alias_database = hash:/usr/local/etc/postfix/aliases alias_maps = hash:/usr/local/etc/postfix/aliases, hash:/usr/local/etc/postfix/aliases-www command_directory = /usr/local/sbin config_directory = /usr/local/etc/postfix daemon_directory = /usr/local/libexec/postfix data_directory = /var/db/postfix debug_peer_level = 2 html_directory = /usr/local/share/doc/postfix mail_owner = postfix mailbox_command = /usr/local/bin/procmail mailbox_size_limit = 524288000 mailq_path = /usr/local/bin/mailq manpage_directory = /usr/local/man message_size_limit = 40960000 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain myhostname = mymailserver.domain.com mynetworks = #list of ip's# myorigin = $mydomain newaliases_path = /usr/local/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/local/share/doc/postfix sample_directory = /usr/local/etc/postfix sendmail_path = /usr/local/sbin/sendmail setgid_group = maildrop soft_bounce = yes unknown_local_recipient_reject_code = 450 virtual_alias_domains = hash:/usr/local/etc/postfix/virtual-alias-domains virtual_alias_maps = hash:/usr/local/etc/postfix/virtusertable virtual_mailbox_base = /var/mail virtual_mailbox_limit = 524288000
