I dislike the gmail trash waiting for 30 days to empty, so I have cron-job running a small Go script that cleans up the trash using the Gmail API. Right now I use Gmail's filters to send stuff I don't like to the trash, but I plan to do the filtering in the script too, when I find the time.<p>I'm still wondering why there isn't a "delete every email from this person automatically" built into either Gmail, or the underlying email spec, which I don't really know anything about.
