I had a couple people tell me my mails went to spam, but I reckon it was just an excuse for not answering. Apart from that, I never had any problem at all in the 5 years I've used them with a custom domain.
Their spam system works great but needs some breaking in: to train it, you need to have marked and deleted 200 spam emails. Only when you delete spam, the system updates its filter. I had some annoying spam that kept landing in my inbox, I had to create an automated "send to spam" rule until the personal spam filter started kicking in.
