/**
Stores the download rules to be used during the IMAP synchronisation phase.

Each rule consists of a bearer types field, and a set of get mail options.
The bearer types are defined by the TCommDbBearer enumeration and it is
possible to specify multiple bearer types for one rule by performing a
bitwise OR operation on the values from the enumeration and passing the
resulting value to the various APIs. The get mail options are defined by
the TImImap4GetPartialMailInfo structure.

There are two sets of download rules, one set for the inbox and one set for
other folders. Generally each of the APIs takes a flag to indicate which set
to operate upon.
