+# Deploy journal-postfix

+# This will install a service that writes mail delivery information
+# obtained from systemd-journal (unit postfix@-.service) to a
+# PostgreSQL database.
+#
+# You can configure the database connection parameters (and optionally
+# a verp_marker) as host vars like this:
+#
+# mailserver:
+#   postgresql:
+#     host: 127.0.0.1
+#     port: 5432
+#     dbname: mailserver
+#     username: mailserver
+#     password: !vault |

+#         XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+#   postfix:
+#     verp_marker: rstxyz
+#
+# If you do not, then you must edit /etc/journal-postfix/main.yml
+# on the destination hosts and run systemctl start journal-postfix
+# manually.
