when I was using Qmail before, I wrote such archive system myself. there are many times people lost their mails and ask to restore all the old emails belong to them. or time to time there are legal issues need to check related emails. I know there are companies who need to keep their mails for 7 years. now there are many mature email archive system in the market so I can just use one of them. but I need to feed the system necessary information to finish the job. QueueID maybe an idea. but if there is some way to hook postfix to get the info it maybe easier. (when using configuration is not possible) I am using postfixadmin+dovecot. for incoming mails I already hook "virtual_transport" and write my script to get every receiver. is there similar hook I can do for outgoing mails?
