Thanks, that is a vey nice feature I did not know about.
I should mention that my strategy of using a cron job to delete

When Gmail returns a spam-related temporary error, it might just be
greylisting the sending client for some time, and maybe the message is
not spam and will eventually be accepted.
This needs to be observed further.
