Getting errors when downloading inbox:

Looks like I misunderstood something about the compression. Could you perform the following steps to help me investigate?

1. figure out affected email: I've just merged #170 which should now print the UI URL whenever a download / decode fails
2. use UI: try to export that URL via the UI as EML. Does that work?

The email accessed using the link is exported successfully using the web ui

Email has an empty body

I changed the code in compression.rs to

use anyhow::{Context, Result};

pub(crate) fn decompress_value(v: &[u8]) -> Result<Vec<u8>> {
    if v.is_empty() {
        return Ok(vec![]);
    }

    lz4_flex::block::decompress(v, v.len() * 12).context("decompression")
}

and now it is working correctly.
