Mail in


With MailIn you can send emails directly to workspaces and cases.


This feature allows unencrypted email to be sent to your intranet portal. As email can be forged, this might contradict your security policy. Please make sure to verify any implications carefully.


This module maps email addresses to workspaces to allow members of the portal to send email directly into the system. For this to work, you need to:

  • Configure a dedicated email domain for your intranet (i.e.
  • Configure your mailserver to forward all incoming email to a script handler.
  • Assign friendly email names to your workspaces (the part before the @).

If you now send an email to such an email address - - it will be created within the workspace.

Configure the email address of a workspace

  • In any workspace, open the settings drawer
  • Click the “Advanced” tab
  • Enter the name part of the desired email address
Configuration of the email address

Configure the import destination folder

By default, imported emails are stored toplevel in the workspace.

You can configure a different destination folder by setting the registry records and optionally ploneintranet.workspace.mailin.folder.title.

Mailserver configuration

Mail comes in through a mail server. So when you want mail for to be handled by smtp2zope and sent to your web server, you should add an alias in your smtp server configuration. Something like this probably works (there might be slight differences depending on which mail server you use): "|/path/to/smtp2zope bin/smtp2zope -v -z localhost:8080 -u /Plone/@@mailrouter-inject 1000000"

The number at the end restricts the maximum size of a message; this is optional, but highly recommended.

Invoking the scripthandler manually

For testing purposes, you can also invoke the script handler manually.

To do so, you need a test email as file.


The system rejects all email coming from email addresses not matching a valid user in the system.

Now you can call the following line from within your zope instance root directory:

cat mail.eml | bin/smtp2zope -v -z localhost:8080 -u /Plone/@@mailrouter-inject


If the sender of that email is not a member of the workspace this mail is routed to, this will fail with a cryptic error ERROR Fail: NotFoundError: Folder not found and an exception on your logs that does not give any hint that the reason for this is that the sender/user cannot access the workspace.

Debugging and testing

A Ploneintranet install with the suite:testing testdata installed comes with an email in the Open Market Committe workspace already.

To add another one:

  • Log in as Christian Stoney
  • Go to the Open Market Committee workspace
  • In ‘Members’, add Alice Lindstrom as a member (if you don’t do that it will error)
  • In ‘Advanced’, set the workspace email address to “mailinworkspace” (without the “” domain part)
  • In a terminal: cat src/ploneintranet/workspace/tests/mailin/mailin_workspace.eml | bin/smtp2zope -v -z localhost:8080 -u /Plone/@@mailrouter-inject
