Email Routing and email attachments

I am very excited with Cloudflare email routing. I was wondering if it’s possible to handle email attachments? may be I can get files hosted in r2?

Currently we are using IMAP servers with node.js scripts listening to it, we would be happy to replace it with Workers.

What you would suggest?

Email workers are still in private beta, so it is currently not known what the capabilities are with it yet.
