how do I set a Thunderbird signature to use a dynamic url's html?

I want to use a dynamic email signature in Thunderbird, that is context aware (depends on date, events in db, etc.)

If I have a PHP that can generate the signature html (i.e. http://www.site.com/email_sign.php) how do I force Thunderbird to use it?

(the only options I see are using static h开发者_StackOverflowtml (whether inline, of from a local system file).

any ideas?

You can use the Signature Switch add-on and a batch file calling wget to achieve what you want. I wrote a simple executable to replace the bat file; you can read about it (and download it if you want to) from http://www.else.co.nz/portfolio/020-code/dynamic-email-signatures

I doubt you can do this simply. Thunderbird does allow scripting via the creation of plugins but I wouldn't personally know how do do it or how easy it might be.

Best answer I can think of would be to set a scheduled task / cron job to download the php to a local file then follow the instructions in the knowledge base, namely:

You can use Thunderbird to create signature files, or you can use your operating system tools to create them—for example, a plain text editor.

Thunderbird does not provide any special place to store signature files. You could create a Signatures directory in your profile to store them, making them easy to back up along with the rest of your profile. Or you could store them somewhere else.

To use a signature file, specify it in Account Settings as the signature for an identity. Check the box "Attach the signature from a file instead" and specify the signature file.

This will work unless Thunderbird caches the HTML internally, however I see no indication in the FAQ that this is the case.

For years I updated the signature for my email client manually – until I got fed up… That’s why I wrote a PHP script to create a randomized signature block automatically from an RSS feed! Check it out: https://github.com/birdy1976/signature :-D
