Hi, I'm pretty sure you need to 1. Configure Zimbra 2. Configure Postfix so it accepts mail that is destined for the Zimbra server, whatever domain that is. Then postfix is configured to relay The mail to the next hop, which sounds like the Zimbra server from your description of the mail flow. 3. Send a test email and look at your Postfix logs to see the email was accepted and processed to be sent along to the Zimbra server.
Postfix logs are pretty good at telling you what the issue is, so test it. Good Luck. -ANGELO FAZZINA UITS Service Manager: Spam and Virus Prevention Mass Mailing G Suite/Gmail ang...@uconn.edu University of Connecticut, UITS, SSG, Server Systems 860-486-9075 -----Original Message----- From: owner-postfix-us...@postfix.org [mailto:owner-postfix-us...@postfix.org] On Behalf Of 9acca9 Sent: Thursday, October 26, 2017 12:34 PM To: postfix-users@postfix.org Subject: Minimun postfix Hello everyone. We have contracted a mail service and we want to make some changes. The idea is to install zimbra on a local server of ours and that zimbra take the mails of the postfix of the contracted service. To test, we are installing a postfix locally on another server. (ie zimbra and postfix are installed on different servers and will be published accessible to the internet with different ip to simulate the scenario we want). I wanted to ask if you can give me a hand with the postfix configuration. For now this is my main.cf file smtpd_banner = $ myhostname ESMTP $ mail_name (Ubuntu) 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 readme_directory = no # TLS parameters smtpd_tls_cert_file = / etc / ssl / certs / ssl-cert-snakeoil.pem smtpd_tls_key_file = / etc / ssl / private / ssl-cert-snakeoil.key smtpd_use_tls = yes smtpd_tls_session_cache_database = btree: $ {data_directory} / smtpd_scache smtp_tls_session_cache_database = btree: $ {data_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. smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = postfix.dominio.org.es alias_maps = hash: / etc / aliases alias_database = hash: / etc / aliases myorigin = / etc / mailname mydestination = $ myhostname, domain.org.us, localhost.domain.com, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [:: 1] / 128 mailbox_size_limit = 8192000 recipient_delimiter = + inet_interfaces = all inet_protocols = all home_mailbox = Maildir / -------------------------------------------------- -------------- Would I have to modify something else ??? -Add mx records in dns and spf and to allow access to Zimbra should configure something else in this configuration? should I add zimbra's public ip in mynetworks ?? The truth that I do not know if it is Zimbra who enters the postfix to download the mails or if it is Postfix who sends them to zimbra Greetings to all and thanks, sorry but I do not know the subject and I'm just getting soaked (although I was watching many tutorials, but from what I saw, I guess the tutorials were more extensive than I need).
