Good point about that much content potentially impacting search.  About how much time would we need to implement something like this?  Then we can run it by Tom.  I don't want to wait too long to have something in place because we've already had 2 periods of down time in the last 6 days and we're going to start to loose users if email isn't reliably delivered.

Well, actually, now that I remember, what we had actually discussed is a specialized blog tool in a specialized community.  So, actually, all of the mailin machinery would be exercised but you wouldn't end up with an enormous number of blog entries stored unnecessarily in your database.  If we're sending a tracer email every 5 minutes, that's 288 blog posts a day.  After just a week, your test community has 2016 blog posts in it, and growing.
 That just doesn't seem sustainable.

So the idea was to just create an object that looks for all the world like a blog for the mailin tool to write a blog entry to, but instead of storing each blog entry it would simply not the time it had last received a blog entry.  So you still have a bunch of transactions, but at least not a ton of data you're trying to store unnecessarily.  Zagy's idea also eliminates the unnecessary transactions, but by using this dummy blog tool, we still exercise all of the mailin machinery end to end.

Title:
  Develop email-in tracer tool

Status in KARL3:
  New

Bug description:
  We don't have a reliable way to know when email-in is wedged.  Rather
  than trying to monitor each part of the end-to-end facility, we should
  instead monitor the failure of a tracer email to be received.

  The idea is that something, somewhere (hopefully inside the OSF NYC
  LAN) sends a tracer email to KARL every N minutes.  This won't be a
  blog entry, as we don't want some dummy blog filling up and the
  content feeds getting blasted.

  Instead, we'll develop a new tool, either as part of a community or
  something hanging off the top.  This tool will record receipt of the
  email.  We'll also make sure that if the tracer wasn't received in the
  last N minutes, monitoring gets triggered.

  Some notes:

  - Exercise as much of the machinery as possible.  We don't really need
  to test the ability to create a blog entry or blog comment.  If it
  goes out of the NYC network, through the Internets tubes, into the
  outer Postfix, through its spam filters, to the inner, through
  repoze.postoffice, and is picked up by the daemon, that will handle
  99% of the problems.

  - Make sure admins like Robert/Nat/Paul can go and see something about
  the tracer. Most likely the admin screen.

  - Document, in that tool, the email address that is used for the To:
  on the tracer.  That lets people send the email manually if they want
  to.
