  7. Invitation e-mail message can be customized (page template modification)


Customizing the invite e-mail

  1. Go to the ZMI

  2. Go to portal_skins, to plone_invite, select the invite_template, customize that

Customizing the invitation sender address

The email address which will be used as the “sender” in invite e-mails is the site-wide e-mail address by default. You can change it via “@@mail-controlpanel”.

If you want to use a different sender address than the site address

  1. Go to the ZMI

  2. Go to the plone_invite tool, go to the ‘properties’ tab, modify plone_invite_email_address


Tested on:

  • Plone 3.2.1, CMF 2.1.2, Zope 2.10.6-final

  • Plone 3.3b1, CMF 2.1.2, Zope 2.10.7-final

  • Plone 3.3.3, CMF 2.1.2, Zope 2.10.9-final


The product relies on a modification of the join_form for its functionality. Using the product alongside another product which also modifies join_form will not work.

1.1.2 (2010-01-04)

  • Fixed bug with import of unused ‘INVITE_EMAIL’ variable from

  • remove setting of site property for PloneInvite email address

1.1.1 (2010-01-04)

  • Fixed bug where invitation email’s sender address was left empty

  • Add property ‘plone_invite_sender_addres’ to tool to use instead of site’s ‘email_from_addres’.

1.1 (2009-12-01)

Plone 3 compatibility fixes by Kees Hink <>. This takes care of just getting the product to work, but there’s more that could be done: see the TODO.

  • Breaks compatibility with Plone 2.5, due to @@authenticator, which is called from the join_form in Plone 3, isn’t available in Plone 2.5.

  • Renamed permissions from “PortalInvite: …” to “PloneInvite: …”.

  • Minor modifications so it works under Plone 3, most notably
    • encode e-mail before sending

  • Enabled self-registration (‘Add portal member’ permission on the site), which is needed to enable new members to register themselves. (Self-registration is protected by the validation on the join_form, so people will only be able to register with an invitation code.)

  • Disabled ‘’ as default value, use site-wide email_from_address as default. (Still customizable through

  • Disable overriding of mailhost settings. ( used to reset the portal’s mailhost settings to localhost:25)

  • Turn on invitation generation for new users by default (5 invitations), this is probably what most sites want. Should be configurable in Plone product settings configlet.

  • Disable bare try-except blocks in invite.cpy

  • Translations:

    • Added PloneInvite.pot and plone.pot

    • Added Makefile for easy creation and updating of translation (.po) files

    • Added Dutch translation

  • Fixed a bug in the user_invites template table, which showed only the invites which did not have enforce_address set.

  • Fixed bug in Extensions/ which added two ‘invite_form’ links to user actions.

  • Added a “FakeMessageFactory” class for translations in controller scripts, see


For future release, these would be nice improvements:

  • Allow modification of invitiations e-mail “Sender” in configlet (currently through ZMI).

  • Modify configlet to enable modification of number of invites to give new users. (default is 5)

  • Include expiration functionality (invitation expires after configurable time period).

  • Do not lose invitations when re-installing.
