It’s only 1 domain I think and they stripped out things like ActiveSync and IMAP a couple years ago IIRC. I use the $1/user/month plan and it’s decent. I don’t use calendars or contacts, so I’m not sure how that stacks up, but the email stuff is good.

The biggest annoyance is that someone used mx, mx2, mx3 for their MX instead of mx1, mx2, mx3, so the dns record indentation doesn’t line up. Lmao.
