About two years ago I did some work to customize the Mozilla Thunderbird product to work with the UVM IMAP servers out-of box:
This project made use of the so-called “ISP Hook” for Thunderbird, loosely documented here:
Unfortunately, it appeared that with the release of Thunderbird 3.0 the ISP Hook was being retired in favor of “autoconfig”:
Autoconfig is a promising project, but unfortunately, it lacks the ability to configure all of the settings previously available in the ISP Hook RDF file:
I had a long look at using the previous “autoconfig” (called “Mission Control Desktop”), and while this approach is powerful, it really requires too much external scripting to be effective as a deployment mechanism (MCD seems more ideally suited to management of systems in a lab environment):
So what is the solution? It involves:
- One expatriate Windows sys admin and reverse-engineering expert.
- A few line of additional shell scripting to our existing build system.
- The ability to distinguish capital and lowercase letters.
While explaining the ISP Hook problem to my colleague Ben Coddington, I noticed that the old Account Configuration dialogs (complete with the create “UVM Email Account” option) was still available under TB3, but that the dialog could no longer be activated following a new installation. Ben said “I’ll bet I can fix that”, and proceeded to unpack every “jar” file in the Thunderbird installation directory.
There is one other minor change… I also set the following additional default option in the global prefs.js file:
This defaults Windows Search integration to “on” in the new account setup dialog. It is a cool new feature that everyone should use (in my opinion).
