Nonurgent delivery, normal delivery, urgent delivery Job Controller options

Job Controller job pool options:  (execution-window string),    (execution-window-string),    (execution-window-string)
The,  , and   Job Controller    options each set an "execution window" for messages of the respective effective processing priority. The default is that all messages are eligible for processing at all times.

An execution window consists of up to five, comma-separated time windows. Each time window is either a daily window (a window of time allowed every day) of the form: hh:mm - hh:mm or a weekly window (a window of time allowed per week) of either of the forms ddd hh:mm - ddd hh:mm or (with the ending day assumed to be the same as the beginning day) ddd hh:mm - hh:mm For instance, a time window 18:00 - 22:00 means between 6:00 PM and 10:00 PM each day. 20:00 - 06:30 means between 8:00 PM and 6:30 AM each night. Sat 06:15 - 15:30 means each Saturday between 6:15 AM and 3:30 PM. Wed 12:00 - Fri 00:00 means between noon Wednesday and midnight Thursday/Friday (the midnight dividing Thursday from Friday). And thus an execution window specifying that processing is allowed any night or all day on weekends could be  22:00 - 05:30, Sat 00:00 - Sun 23:59 Note that the MTA can be configured to modify messages&#x27; effective processing priority based on certain criteria such as message size, see  the   channel  options, or via the MTA&#x27;s non-standard  Sieve extension " ". As of the 8.0 release, an explicitly specified MT-PRIORITY value for a message will override the older Priority: header value or the MTA&#x27;s size-based effective processing priority adjustments, and in particular take precedence for Job Controller delivery execution window purposes. Only the MTA&#x27;s non-standard Sieve extension " " can override an explicitly specified MT-PRIORITY value.
