I have a problem with ispconfig and postfix. Postfix accepts mail for any existing username at any existing domain. Let's say domain1.com has a user called web1_user1. Postfix now not only accepts mail to [email protected] whicht it should but also to [email protected], [email protected] and so on. The wrongly accepted mail is all store in the account of web1_user1. Postfix will also accept mails for all system accounts like [email protected] or [email protected]. What can I do so that postfix only accepts mail if the username is configured for that specific domain? My /etc/postfix/main.cf Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h # TLS parameters smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = sub.domain.net alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname relayhost = mynetworks = 127.0.0.0/8 #mailbox_command = # macht wohl ispconfig mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = all smtpd_sasl_local_domain = ## BERNY: --> vielleicht liegt es an SASL smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes # Hier die ganze Spamabwehr: smtpd_recipient_restrictions = permit_sasl_authenticated, reject_invalid_hostname, # Mit Vorsicht zu geniessen: reject_unknown_hostname, reject_non_fqdn_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_unknown_recipient_domain, permit_mynetworks, reject_unauth_destination, reject_rbl_client zen.spamhaus.org, reject_rbl_client list.dsbl.org, reject_rhsbl_client rhsbl.sorbs.net, reject_rhsbl_sender rhsbl.sorbs.net body_checks = pcre:/etc/postfix/body_checks.pcre header_checks = pcre:/etc/postfix/header_checks.pcre smtpd_tls_auth_only = no smtp_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom #home_mailbox = Maildir/ # macht wohl ISPConfig anders virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names
This is normal as you're using system user names before the @. Try to use aliases instead (they're defined in /etc/postfix/virtusertable).
