Products.PrintingMailHost

This is a hack. :)

This product, when installed, will check if Zope is running in debug mode, and if so, monkey patch (that is, grab the internals of, squeeze tight, then rip hard, just like monkeys do) Zope's MailHost class, meaning that any and all uses of a MailHost will be "fixed" so that instead of sending mail, it prints messages to the zope event log.

This is useful if you don't have a local mailhost for testing, or if you prefer not to spam the crap out of yourself whilst finding out if your bulk mail script is working.

If Zope is not running in debug mode, it will not install itself. However, I wouldn't recommend putting it on a production site. You never know what those monkeys may get up to...

You can optionally enable the PrintingMailHost with an environment variable as of version 0.3. See the installation instructions for more information about how to use it.

Compatibility

Works on Plone 3.3, Plone 4, Plone 5.0, 5.1 and 5.2 (in Python 2.7, 3.6 and 3.7).

Products.PrintingMailHost Installation

To install Products.PrintingMailHost into your Plone instance in buildout, you can do this:

• Add Products.PrintingMailHost to the list of eggs to install, e.g.:

  [instance]
  ...
  eggs =
      ...
      Products.PrintingMailHost
  

• If you want to enable PrintingMailHost when debug-mode is off:

  [instance]
  ...
  environment-vars =
      ...
      ENABLE_PRINTING_MAILHOST True
  

• If you want to disable PrintingMailHost when debug-mode is on:

  [instance]
  ...
  environment-vars =
      ...
      ENABLE_PRINTING_MAILHOST False
  

• If PrintingMailHost is enabled, and you additionally want to send each email to a fixed address, you can add another environment variable:

  [instance]
  ...
  environment-vars =
      ...
      PRINTING_MAILHOST_FIXED_ADDRESS admin@example.org
  

  Or multiple addresses separated by spaces:

  PRINTING_MAILHOST_FIXED_ADDRESS one@example.org two@example.org
  

  For clarity: this first prints the email, with the original recipient address, and then sends an actual email with the same contents to the fixed address you have specified. The original recipient is visible in the To: field. It is similar to receiving a blind carbon copy (bcc) of an email, except that the original recipient never gets the email.

• Re-run buildout in order to make any of the above changes active:

  $ ./bin/buildout
