@class mailbox_status (sockets) discussion VS. class mailbox_msg_info (sockets)
@abstract compare these two similar classes and their functions
@Discussion:
class mailbox_status is used by function IMAP_STATUS
class mailbox_msg_info is used by function IMAP_MAILBOXMSGINFO
These two functions / classes are similar, here are some notes on their usage:
Note 1):
IMAP_MAILBOXMSGINFO is only used for the folder that the client is currently logged into,
for pop3 this is always "INBOX", for imap this is the currently selected (opened) folder.
Therefor, with imap the target folder must already be selected (via IMAP_OPEN or IMAP_REOPEN)
Note 2):
IMAP_STATUS is can be used to obtain data on a folder that is NOT currently selected (opened)
by the client. For pop3 this difference means nothing, for imap this means the client
need NOT select (i.e. open) the target folder before requesting status data.
Still, IMAP_STATUS can be used on any folder wheter it is currently selected (opened) or not.
Note 3):
The main functional difference is that one function returns size data, and the other does not.
imap_mailboxmsginfo returns size data, imap_status does NOT.
This size data adds all the sizes of the messages in that folder together to get the total folder size.
Some IMAP servers can take alot of time and CPU cycles to get this total,
particularly with MAILDIR type imap servers such as Courier-imap, while other imap servers
seem to return this size data with little difficulty.
