From 0853c2afdc2ddba11692ef17bb859104d47071e0 Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Tue, 14 Jan 2014 05:58:33 +0100 Subject: Fix catchall resolution. It has to be performed last, to give a chance to be accepted as a regular mailbox. We introduce a new, dedicated, smtpd daemon whose only purpose is to resolve catch-alls. --- roles/MX/templates/etc/postfix/main.cf.j2 | 27 +++++++++++----------- .../templates/etc/postfix/virtual/alias_maps.cf.j2 | 6 +++++ .../etc/postfix/virtual/catchall_maps.cf.j2 | 7 ++++++ .../etc/postfix/virtual/mailbox_domains.cf.j2 | 8 +++++++ .../etc/postfix/virtual/reserved_alias_maps.j2 | 4 ++++ .../postfix/virtual/transport_catchall_maps.cf.j2 | 8 +++++++ .../etc/postfix/virtual/transport_lists_maps.cf.j2 | 12 ++++++++++ .../postfix/virtual/transport_mailbox_maps.cf.j2 | 12 ++++++++++ .../virtual/transport_reserved_maps.pcre.j2 | 6 +++++ 9 files changed, 76 insertions(+), 14 deletions(-) create mode 100644 roles/MX/templates/etc/postfix/virtual/alias_maps.cf.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/catchall_maps.cf.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/mailbox_domains.cf.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/reserved_alias_maps.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/transport_catchall_maps.cf.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/transport_lists_maps.cf.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/transport_mailbox_maps.cf.j2 create mode 100644 roles/MX/templates/etc/postfix/virtual/transport_reserved_maps.pcre.j2 (limited to 'roles/MX/templates/etc') diff --git a/roles/MX/templates/etc/postfix/main.cf.j2 b/roles/MX/templates/etc/postfix/main.cf.j2 index d301aaf..c0da5e7 100644 --- a/roles/MX/templates/etc/postfix/main.cf.j2 +++ b/roles/MX/templates/etc/postfix/main.cf.j2 @@ -19,7 +19,7 @@ append_dot_mydomain = no #
