They say you get what you pay for, and with Canaca, that would be not much... I was using IMAPS for a long time, and then they just decided to shut the port down without any warning. They provide ssh access, but they refuse to provide IMAPS under the same terms... Either they don't have a clue what they're doing, or they just don't care.
Their reliability isn't very good either.

Spend a little more cash and get a host that won't frustrate you. Also, don't lock in a rate until you've tested their service for a couple months at least.
