Custom columns based on mail headers

[hashar]

Just found your plugin which is kind of nice. It seems you can add an interface to let people add whatever mail headers they might need. There is a mailnews.customDBHeaders option which is a space separated and lower case list of headers that Thunderbird will index when receiving a new mail. For previously received emails, one needs to 'repair' the folder to force the reindexation and populate the fields values in the .msf file.

An interface can then build to add a column based on the field in customDBHeaders, this way you scale out the addition of new columns / headers to the end user instead of having to update your extension on each request :]

Milestone 5.0 removed.
With version 5.0 it will be possible to add any custom column directly from the addon preference panel.
The feature to show any custom db header not linked with a custom column wil be added in a future release.

Hi. I wish to also add custom header data into the column view. However, I do not understand how to create a column for 'return-path' for example.

• I have typed in return-path for the ID and for Mail Header boxes, however I am getting no joy.
• Could anyone explain?
  Many thanks!

First you need to add a new custom column, with the editor:

Put return-path as "ID" and "Mail Header".
The other fields are for display, so put in there what you want.

"Enabled" must be selected.

After that you need to select the new column from the messages list columns picker.
Please consider that the new column will be filled only for new received mails.

I have followed these instructions and repaired the folder in order that the index be rebuilt but the return-path still does not show up. Any suggestions?

In the last Thunderbird versions the index rebuild doesn't work to force a new column to be indexed. Which version are you using?
Is the new column filled for newly arrived emails?

I also tried adding Return-Path, it doesn't work for current and new messages, it's empty. Other custom headers work, maybe it's related to https://bugzilla.mozilla.org/show_bug.cgi?id=494100

@dexter777 I think you're right, this problem is related to that old Thunderbird bug.
Thank you.
