Been really enjoying the Email routing but it's only 1/2 the solution, would very much love to be able to at least do SMTP, or better yet, provide IMAP/POP accounts. Improvmx does this but I'd much rather have all services in the same location. Is this on the roadmap at all?

I’d be surprised if there was IMAP/POP accounts as email routing just forwards emails and doesn’t store them. Last I recall they don’t want to support sending outbound emails (that aren’t verified) as they don’t want to deal with spam lists
