I'm very happy with fastmail too but I'm only paying for one inbox. If OP needs half a dozen users, then that's $300 a year, which is excessive for light personal use. I suppose as they only need SMTP they could set them all up as identities on a single inbox but that's not what fastmail is meant for.
