Not all messages need to be treated equally. When sendmail processes the messages in its queue, it sorts them by priority. [56] The priority that is given to a message is calculated once, when it is first created, and adjusted (incremented or decremented) each time it is processed in the queue. You can think of priority as a cost, where mail with the lowest priority number (lowest cost) is handled first. The formula for the initial calculation is:
priority = nbytes - (class * z) + (recipients * y) The items in this calculation are as follows :
The forms of the RecipientFactor option are as follows: O RecipientFactor= factor configuration file (V8.7 and later) -ORecipientFactor= factor command line (V8.7 and later) define(`confWORK_RECIPIENT_FACTOR', factor) mc configuration (V8.7 and later) Oy factor configuration file (deprecated) -oy factor command line (deprecated) The argument factor is of type numeric . If that argument is missing, the default value is zero. If the entire RecipientFactor option is missing, the default value is 30000 (thirty thousand). The default for the mc technique is to omit this option. The RecipientFactor option is not safe. If specified from the command line, it can cause sendmail to relinquish its special privileges. |
