Careful - don't rely on fastmail for XMPP. I switched to them based on them having that, since I used it a lot with Gmail. Then I found out that fastmail is running some super wobbly XMPP server which kicks you off any time you really get going really quickly in a conversation. I've opened multiple tickets, and all they can say is "sorry" and "we know about it" and "we're working on it", but actual fixes still haven't come. Having a solid chat experience obviously is not high on their priority list.
