Functions of the subfolder under mque folder

This is for IMSS 7.0 on Windows platform. If you are wondering what are the subfolders for, read the following:

Location of the folder C:\Program Files\Trend Micro\IMSS\mque

TMP folder - Incoming mails
INBOX - mails ready for scanning
PROC - Scanning phase
OUTBOX - Delivery phase
RESEND - for mail resending
FROZEN - mails that has already reached the maximum retry period.

These folders are used by IMSS when processing mails. Once IMSS received a mail, these will be placed on TMP folder. Once IMSS is not free to process the mail, then the particular mail will be moved to INBOX folder. Then IMSS will move the mail to PROC folder for scanning process. Once scanning is finished, the mail will be moved to OUTBOX folder for delivery. If the mail cannot be sent, the mail will be moved to RESEND folder for resending. If the mail already reached the maximum retry limit, then the mail will be moved to FROZEN folder.
