Hi there. I've just followed this tut: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-debian-lenny First off, extremely greatful for that write up, had searched for a couple of days for something as indepth with out going too far over the top, and came up empty handed. First off, I had to do this: Code: chown amavis:amavis /var/dcc/ Or i got this error: Code: ==> mail.err <== Mar 5 22:03:33 stubbed dccproc[30799]: /var/dcc: Permission denied So fixed that problem, now I'm getting the 'loops back to myself' error: Code: ==> mail.log <== Mar 5 23:40:34 stubbed postfix/smtp[4113]: B51DF2F02C2: to=<[email protected]>, relay=none, delay=0.04, delays=0.03/0.01/0/0, dsn=5.4.6, status=bounced (mail for mail.domain.co.nz loops back to myself) Code: Final-Recipient: rfc822; [email protected] Original-Recipient: rfc822;[email protected] Action: failed Status: 5.4.6 Diagnostic-Code: X-Postfix; mail for mail.domain.co.nz loops back to myself I followed what was said in this thread: http://howtoforge.org/forums/showthread.php?t=20499 But it appears that I'm doubling up on myself. Here is my config info: Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes config_directory = /etc/postfix content_filter = amavis:[127.0.0.1]:10024 html_directory = /usr/share/doc/postfix/html inet_interfaces = all mailbox_size_limit = 0 message_size_limit = 30720000 mydestination = mail.domain.co.nz, localhost, localhost.localdomain myhostname = mail.domain.co.nz mynetworks = 127.0.0.0/8 myorigin = /etc/mailname proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps readme_directory = /usr/share/doc/postfix receive_override_options = no_address_mappings recipient_delimiter = + relayhost = smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf virtual_alias_domains = virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_gid_maps = static:5000 virtual_mailbox_base = /home/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_maildir_limit_message = "The user you are trying to reach is over quota." virtual_overquota_bounce = yes virtual_uid_maps = static:5000 Is anyone able to shed any light on the situation?
