Sounds easy enough – I'll fork look into it and get back with a PR.

Thanks for taking the time to report, Phil. I wonder if an HTML change suggested by this SO post would fix the issue? The post suggests using Content Type multipart/related instead of multipart/mixed.

Tagging @seshrs for his opinion.

Sorry for the delay, I was pretty busy during the week. But today I found some time to further play with this.
I went and edited Thunderbirds mbox file changing multipart/mixed to multipart/related for the message in question and, lo an behold, the inline image is now correctly displayed in thunderbird.

Thanks @philpagel this is really helpful. Let me know if you feel up to trying a fix. I think it might be a one-line change.

Thanks for the link! I'll play with that and report on the result.
