in log database create table "statuses" structure
| id | queued_at | sending_at | from | rcpt | message_type | message_id | status |
|---|
message_type is string from "X-Postmaster-Msgtype" header
message_id is string from "Message-Id" header
in queue database create table "queues" structure
| id | created_at | updated_at | message_type | message_id | from | from_hostname | rcpt | rcpt_hostname | data | repeat | later_status |
