RSS Feeds Return 503 for Thunderbird

Original Request:

I'll use my own feed as an example, but I'm seeing it with other feeds, as well.

If I visit <https://pinterface.dreamwidth.org/data/atom> in Firefox (v 134.0), the feed loads just fine.

If I use that same URL in Thunderbird (v 115.18.0), I get a 503:

```
<!DOCTYPE html>
<html>
    <head>
        <title>503 Backend fetch failed</title>
    </head>
    <body>
        <h1>Error 503 Backend fetch failed</h1>
        <p>Backend fetch failed</p>
        <h3>Guru Meditation:</h3>
        <p>XID: 753690</p>
        <hr>
        <p>Varnish cache server</p>
    </body>
</html>
```

(I know triple-backticks don't actually generate a codeblock, just delineating.)

This has been happening off and on for a while (a couple of weeks, maybe?). Wild guess is bot detection gone awry, but that's a pretty big WAG.

(Possibly the same underlying issue as reported in 49818?)
