No content for large books from gutenberg.org

Hi @fivefilters,

I wrote a config for the gutenberg project yesterday for a wallabag user, which works fine in wallabag and my self-hosted FTR.

But I can’t get any content on ftr.fivefilters.net and push-to-kindle for large books. Are there some regulations for this domain or the size of content?

I do not need the support for gutenberg.org for FTR or P2K, I was just wondering. Gutenberg also directly exports to some epub formats, including Kindle. So, no need to use P2K.
