I also use this. Pros: super cheap. <$2/mo for all my custom email addresses and routing rules. Nothing else came close - everything else I found would make me pay per email address even if that address receives an average of 0 emails per month. The wildcard suffixes are really nice as well - they use _ instead of gmail's + (I've had issues with gmail's version as it sometimes is transparently removed, or sometimes the form doesn't consider + a valid character).

Cons: UI is bad, so you'll want to access through a client. 1 person shop. Not audited AFAIK.
