I've managed to break Anker email support
Update on the Anker email loop: The system is still broken. I have now received 49 automated emails for a single warranty claim, arriving every 20 minutes. It ignores my replies. If anyone from Anker sees this, my ticket is TNA1681493935. Please free my inbox.
@joebeone Mailer rules are your friend…

@SteveBellovin @joebeone

procmail (and maybe MTA filter rules) for the win. :)

I have seen something like this from my bank. Duplicate emails every hour or so stopping after a day.

My guess is some interaction with upstream postgrey instance. I have never fully diagnosed.
