According to http://savannah.nongnu.org/patch/index.php?6297
imap support shold be in duplicity, but the current version (5.06) does
not ship with a
generic imap backend, but with a gmail-backend.
The comments on said patch read "(google IMAP works a bit different)",
so I assume that
just replacing the hard-coded references to gmail in gmailbackend.py by
another imap-server will not work...will it?
I have no way to test this at all. If someone has the means to test
against a generic IMAP server, please let us know how it works.
