ThunderBirdExtension FAQ


This guide discusses commonly encountered problems with the extension. Ensure you are using the latest stable release of the extension at all times as many problems are fixed with newer releases. If you encounter a new problem or find these solutions dont work for you please report a bug with full details of your case.

Why is the PennyPost extension/add-on so big?

The extension size is large because it bundles another algorithm besides hashcash called memory-bound. This is a pricing algorithm similar to hashcash. You can find details of this algorithm here: MBound. This algorithm requires a 16MB fixed table to work and taxes the memory rather than the CPU. Hashcash taxes the CPU alone.

Can I download the extension without MBound? I dont want to download 16MB.

The extension by itself does not contain MBound or HashCash. The PennyPost CommandLine does.
The CommandLine is included in the extension package downloadable on sourceforge.net.
If you want the extension without the CommandLine download it here.

Also see this tracker for information on removing MBound support from the PennyPost CommandLine.

Is Stamping email the same as Signing? Encryption?

No. Signing email assures the receiver of the senders identity. Stamping email does not assure the receiver about the senders identity. It only assures the receiver that the sender spent computer time generating the PostageStamp. If you want to sign or encrypt email you want Enigmail.

I've installed the extension version 1.2.1 and now my email appears completely messed up!

This occurs due to view all headers option remaining enabled after install. To fix this, go to the View Menu and select Headers -> Normal.

Why does the extension not update automatically

Auto-update has been implemented since version 1.3
This will probably not happen until Mozilla moves this extension to its public site, so the mean time you'll need to keep the extension up-to-date manually.

Stamp & Send icon missing from the customize window

This icon will appear only when you customize toolbars for the "message compose window" (the one that opens when you compose or reply to an email) of Thunderbird and not the main window. You can still find Stamp & Send options in the File menu of the message compose window.

The extension says "stale" for all stamps

This issue is fixed in extension version 1.2.4 and above. Please upgrade and it should be resolved.

No valid stamp is detected even on stamped email

This is due to Bug 1788340 which affects some instances of the Penny Post ThunderbirdExtension version 1.2 and below only.
This has been fixed in versions 1.2.1 and beyond. Users should upgrade to fix the issue.
If you already have the latest version and still face this problem, try enabling All Headers by selecting View Menu - Headers - All

Stamp verification takes ages

Check if the path of the stamp program and Java executable is correct in the extensions preferences under External Program Paths.
Are you using the correct version of Java?

Stamp generation takes ages

Check if the path of the stamp program and Java executable is correct in the extensions preferences under External Program Paths.
Are you using the correct version of Java?
If you have a slow machine you might want to reduce the stamp costs. Read the ThunderBirdExtensionAdvancedConfiguration.

I see the message "The stamp could not be verified- [Exception..."

Check if the path of the stamp program is correct in the extensions preferences under External Program Paths.

My Encryption & Signature icons are missing

No, they are still there, you have to scroll-down to them. The icons appear to be to programmed to display in the vertical center of the headers, rather than at the top. You can see this if you disable Penny Post and look for the security icons while displaying full-headers. Getting the icons to the top may require filing a bug report against both the Enigmail extension and X.509 security in Thunderbird.
