1and1 and ipower are cheap and fairly good (Score 1)

1and1.com will give you 2GB of mail, 5 mailboxes, POP, IMAP, spam filtering, etc for $12/year. ipower.com will give you 200 mailboxes for $15/year. Both support SSL and alternate ports. I've used 1and1 for ten years, and ipower for one year. They're both pretty reliable and responsive. If e-mail is the criterion, I'd go with 1and1 - you can't train the ipower spam filter, and it's only mediocre.
