[*] Now errors detected in JPEG images (e.g. embedded to HTML message) are only logged to the ex_log.txt when a command line option /REPORT_JPEG_ERRORS is set.
[*] If an IMAP connection is closed during IDLE command or when no command is active, i.e. between NOOPs, no message that connection closed is displayed to the log in the status bar (however, if a protocol log is turned on, the message is logged there)
[*] (#0008522) Error "The message is sent but could not be moved from Outbox to the Sent folder" will now not be obscured by lesser subsequent messages
