*** Testing imap_close() : usage variations ***
Create a temporary mailbox and add 3 msgs
New mailbox created

-- Iteration 1 --
bool(true)
CL_EXPUNGE was not set, 3 msgs in mailbox

-- Iteration 2 --
bool(true)
CL_EXPUNGE was set

-- Iteration 3 --
imap_close(): Argument #2 ($flags) must be CL_EXPUNGE or 0

-- Iteration 4 --
imap_close(): Argument #2 ($flags) must be CL_EXPUNGE or 0

-- Iteration 5 --
imap_close(): Argument #2 ($flags) must be CL_EXPUNGE or 0
