Dear friends and coulegues, I have an ISPConfig (Installed with the perfect apache server 8.4 tutorial) server with several IP and Domains on it. Since the first day of installation i'm having a problem with lots of rejected messages, because of Reverse DNS does not match SMTP Banner. Whatever i do with Postfix Main.cf and Master.cf, mails are send from the Main(management) IP and domain and not from the IP/Domain sending it... Lets say that this are the users: localhost = 1.1.1.1 = main1.com (management) 2nd user = 2.2.2.2 = Domain2.com 2rd user = 2.2.2.2 = Domain3.com (2nd domain of the same user) 3rd user = 3.3.3.3 = Domain4.com... Here is My Postfix master.cf, please tell me what should i chainge. Bellow it, i will post the Main.cf. Please let me know if there are other setting that i should change. Many thanks for your support and communication MASTER.CF # ========================================================================== 127.0.0.1:smtp inet n - n - - smtpd -o myhostname=localhost 1.1.1.1:smtp inet n - n - - smtpd -o myhostname=mail.main1.com 2.2.2.2:smtp inet n - n - - smtpd -o myhostname=mail.domain2.com 2.2.2.2:smtp inet n - n - - smtpd -o myhostname=mail.domain3.com 3.3.3.3:smtp inet n - n - - smtpd -o myhostname=mail.domain4.com #smtp inet n - - - 1 postscreen #smtpd pass - - - - - smtpd #dnsblog unix - - - - 0 dnsblog #tlsproxy unix - - - - 0 tlsproxy submission inet n - - - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject smtps inet n - - - - smtpd -o syslog_name=postfix/smtps -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject pickup unix n - - 60 1 pickup cleanup unix n - - - 0 cleanup qmgr unix n - n 300 1 qmgr #qmgr unix n - n 300 1 oqmgr tlsmgr unix - - - 1000? 1 tlsmgr rewrite unix - - - - - trivial-rewrite bounce unix - - - - 0 bounce defer unix - - - - 0 bounce trace unix - - - - 0 bounce verify unix - - - - 1 verify flush unix n - - 1000? 0 flush proxymap unix - - n - - proxymap proxywrite unix - - n - 1 proxymap smtp unix - - - - - smtp relay unix - - - - - smtp # -o smtp_helo_timeout=5 -o smtp_connect_timeout=5 showq unix n - - - - showq error unix - - - - - error retry unix - - - - - error discard unix - - - - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - - - - lmtp anvil unix - - - - 1 anvil scache unix - - - - 1 scache maildrop unix - n n - - pipe flags=DRhu user=vmail argv=/usr/bin/maildrop -d vmail ${extension} ${recipient} ${user} ${nexthop} ${sender} uucp unix - n n - - pipe flags=Fqhu user=uucp argv=uux -r -n -z -a$sender - $nexthop!rmail ($recipient) ifmail unix - n n - - pipe flags=F user=ftn argv=/usr/lib/ifmail/ifmail -r $nexthop ($recipient) bsmtp unix - n n - - pipe flags=Fq. user=bsmtp argv=/usr/lib/bsmtp/bsmtp -t$nexthop -f$sender $recipient scalemail-backend unix - n n - 2 pipe flags=R user=scalemail argv=/usr/lib/scalemail/bin/scalemail-store ${nexthop} ${user} ${extension} mailman unix - n n - - pipe flags=FR user=list argv=/usr/lib/mailman/bin/postfix-to-mailman.py ${nexthop} ${user} dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} amavis unix - - - - 2 smtp -o smtp_data_done_timeout=1200 -o smtp_send_xforward_command=yes 127.0.0.1:10025 inet n - n - - smtpd -o content_filter= -o local_recipient_maps= -o relay_recipient_maps= -o smtpd_restriction_classes= -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks=127.0.0.0/8 -o strict_rfc821_envelopes=yes -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks -o smtp_send_xforward_command=yes -o disable_dns_lookups=yes 127.0.0.1:10027 inet n - n - - smtpd -o content_filter= -o local_recipient_maps= -o relay_recipient_maps= -o smtpd_restriction_classes= -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks=127.0.0.0/8 -o strict_rfc821_envelopes=yes -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks -o smtp_send_xforward_command=yes -o milter_default_action=accept -o milter_macro_daemon_name=ORIGINATING -o disable_dns_lookups=yes

Thank you for the fast answer Florian, should i put it on every line with the designated IP? (I thought that because of the beginning of the setting i dont have to in ex: 2.2.2.2:smtp inet n - n - - smtpd -o myhos) Should i do it like this? 2.2.2.2:smtp inet n - n - - smtpd -o myhostname=mail.domain2.com -o smtp_bind_address=2.2.2.2
Try: Code: 1.1.1.1:smtp inet n - n - - smtpd -o myhostname=mail.main1.com -o smtpd_bind_address=1.1.1.1
Thanks Florian, But unfortunately it doesn't solve the problem. I entered the whole definition for all domains and IPs, like this: 2.2.2.2:smtp inet n - n - - smtpd -o myhostname=mail.domain2.com -o smtp_bind_address=2.2.2.2 -o syslog_name=postfix-mail.domain2.com -o smtp_helo_name=mail.domain2.com And still in the mails os at SMTP tests, mail is send from the mangement server and IP: 1.1.1.1 main.com I send a mail to [email protected] from [email protected] and got: host mx3.hotmail.com[65.55.37.72] said: 550 SC-001 (COL004-MC1F56) Unfortunately, messages from 1.1.1.1 weren't sent. Please contact your Internet service provider... Maybe i should put also something else in the main/master.cf or ISPc settings?
Postfix uses roundrobin for the ips. BUt you can define transport-maps so example.com will be sent over 1.1.1.1 and example2.com over 2.2.2.2
I tried a lot of tutorials but nothing solved. Can you please give me an example how should i write the transport and in which file? I tried in: /var/lib/mailman/data/transport-mailman and entered: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - domain1.com smtp:[mail.domain1.com] domain2.com smtp:[mail.domain2.com] domain3.com smtp:[mail.domain3.com] - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - and then: postmap /var/lib/mailman/data/transport-mailman But this forms some kind of loop and mails are not usable...
you can use /etc/postfix/sender_transports. i.e. Code: @example1.com smtp1: @example2.com smtp2: and in master.cf: Code: smtp1 unix - - n - - smtp -o smtp_bind_address=1.1.1.1 -o smtp_helo_name=example1.com -o syslog_name=postfix-customer-example1.com smtp2 unix - - n - - smtp -o smtp_bind_address=2.2.2.2 -o smtp_helo_name=example2.com -o syslog_name=postfix-customer-example2.com Add it to postfix: Code: postconf -e "sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport" postmap the file and reload postfix: Code: postmap hash:/etc/postfix/sender_transport postfix reload
