I need a new e-mail spam blocking service…

So I’m looking for a new service to replace a service that I’ve loved, Mailblocks, they’re shutting their doors today (or tomorrow). I want a spam blocking service that uses captchas (I do understand the pros and cons but most importantly I’m aware that it does work and I do check my pending box for real messages). I see there are two other companies out there that look similar, SpamArrest.com and iPermitMail.com. I’d really like to use IMAP for my mail.

Can anyone tell me if they support IMAP? Or can anyone recommend these companies in particular? Or some other companies with similar service? It’s looking like SpamArrest will be my choice but I am looking for options.

(Later) I’ve discovered that SpamArrest uses IMAP (found some info here). But it doesn’t let you see the unverified mail via IMAP (Mailblocks let you see it and you could drag from there to the INBOX and it automatically verified it) this would be really useful. I’d still like to check out others, because I’d really like to be able to do this (it worked really well for me in the past). Even if it wouldn’t auto verify it’d be nice to see it (with IMAP I can pull the mail down and look at it offline and it still keeps a copy on the server.
