[Dovecot] dovecot and cloudfile systems

[Timo Sirainen]

What you're trying to do is quite unlikely to work with any IMAP server / cloud filesystem combination. And if it does work, the performance will most likely be horrible. Of course, if it does work with any kind of a combination I'm interested in knowing about it.

I think I will just try on the amazon cloud, see if the "buckets" have the same problems, everything else is near done its just this mail problem I am having. Rackspaces solution is to pay them 1250 dollars for a minimum of 5 hours of development and this type of job hasn't even been quoted from them.

Buy up businesses that support that development so they can keep the good in house and release just enough so they can profit from the development. Then again they are backed by at&t and then with at&t you are dealing with the government. The government loves things that are in development as long as they don't develop. lol
