Any help where to look and what I must do? This is my main.cf Code: inet_protocols = all biff = no mail_spool_directory = /var/mail canonical_maps = hash:/etc/postfix/canonical virtual_alias_maps = hash:/etc/postfix/virtual virtual_alias_domains = hash:/etc/postfix/virtual relocated_maps = hash:/etc/postfix/relocated transport_maps = hash:/etc/postfix/transport sender_canonical_maps = hash:/etc/postfix/sender_canonical masquerade_exceptions = root masquerade_classes = envelope_sender, header_sender, header_recipient mydomain = mydomainname.name myhostname = server.mydomainname.name myorigin = $mydomain mynetworks = 127.0.0.0/8 program_directory = /usr/lib/postfix inet_interfaces = all mydestination = $myhostname, localhost.$mydomain, $mydomain defer_transports = mynetworks_style = subnet disable_dns_lookups = no relayhost = home_mailbox = Maildir/ mailbox_command = mailbox_transport = strict_8bitmime = no disable_mime_output_conversion = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_client_restrictions = smtpd_helo_required = no smtpd_helo_restrictions = strict_rfc821_envelopes = no smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_local_domain = smtpd_use_tls = yes smtp_use_tls = yes smtp_tls_auth_only = no smtpd_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes stmpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom alias_maps = hash:/etc/aliases mailbox_size_limit = 0 message_size_limit = 10240000

i notice in mail.err those errors Code: Aug 18 12:39:09 server.mydomainname.name imapd: authentication error: Input/output error Aug 18 12:39:34 server.mydomainname.name imapd: authentication error: Input/output error Aug 18 12:39:35 server.mydomainname.name authdaemond: Connection to server 'pgsql.example.com' userid 'admin' database 'template1' failed. Aug 18 12:39:35 server.mydomainname.name authdaemond: could not translate host name "pgsql.example.com" to address: Name or service not known I edited authdaemonrc like this #authmodulelist="authuserdb authpam authpgsql authldap authmysql authcustom authpipe" authmodulelist="authuserdb authpam authcustom authpipe" seems like don't have errors now, but i cant find why i sent mail from different domains
OK i found solution in http://www.postfix.org/uce.html#smtpd_sender_restrictions smtpd_sender_restrictions solve my problem Thank you to all
