Postfix has no support for senders to specify "do not deliver
this message after X" (i.e. no per-message expiration time).
Postfix explicitly does not support other programs reading or
manipulating Postfix queue files. If you do this then you do
so at your own risk.
Postfix has no support for control over the queue by non-Postfix
programs. Allowing a non-Postfix program to decide if mail goes
into the active queue does not solve your problem. Postfix will
retry delivery until the message is too old.
Also, you need to respect mailing list etiquette. Put your reply
BELOW the text that you reply to, and do reply with the entire
previous message if it is longer than a dozen or so lines.
