For historical reasons we still run DJabberd at FastMail so I had to add support for this myself. You might try this patch: https://github.com/fastmail/DJabber

For historical reasons we still run DJabberd at FastMail so I had to add support for this myself. You might try this patch: https://github.com/fastmail/DJabberd/commit/144c4431f36e5ea371aeeaa4692f6d81fae196ff https://github.com/fastmail/DJabberd/commit/144c4431f36e5ea3...

I might have made some stupid error that makes the crypto entirely useless but considering yesterday it was all in cleartext anyway I think I can live with it ;)
