I am getting ready to step up my Postfix version from postfix-2.3.3-2.1.el5_2 (Package maintainers version) to Simon's binary RPM 2.7.0 package. Currently I checked out the 'Release Notes":
http://de.postfix.org/ftpmirror/official/postfix-2.7.0.RELEASE_NOTES >From what I read, no functionalist has been removed but I am stepping up from such an old version granted it's the latest version available from Red Hat Enterprise Linux, there could be problems with my particular configuration. I was wondering if I did decide to step up this weekend during some downtime, how difficult would it be to simply drop my current 2.3.x configuration into the 2.7.0 build on my Red Hat Enterprise Linux server? I attached my 'postfconf -n' below because maybe someone will see something that would break or not work well in 2.7. Thanks for any support! Sadly there are no guides for configuration on 2.7 from scratch since it's so new. ###Postconf -n### address_verify_sender = $double_bounce_sender alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix content_filter = amavisfeed:[127.0.0.1]:10024 daemon_directory = /usr/libexec/postfix home_mailbox = mail/ html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man message_size_limit = 20480000 mydestination = $myhostname, $mydomain, mail.$mydomain mydomain = iamghost.com myhostname = mail.iamghost.com mynetworks = $config_directory/mynetworks myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES recipient_delimiter = + relay_domains = sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_tls_security_level = may smtpd_banner = $myhostname ESMTP smtpd_data_restrictions = reject_unauth_pipelining, permit smtpd_delay_reject = yes smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, permit smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, reject_unlisted_recipient, check_policy_service unix:postgrey/socket, check_sender_access hash:/etc/postfix/sender_access, check_helo_access pcre:/etc/postfix/helo_checks.pcre, check_client_access hash:/etc/postfix/client_access, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, permit smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_unknown_reverse_client_hostname, permit smtpd_tls_auth_only = yes smtpd_tls_cert_file = /srv/ssl/ghost.crt smtpd_tls_key_file = /srv/ssl/ghost.key smtpd_tls_loglevel = 1 smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:/var/spool/postfix/smtpd_tls_cache smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550
