DeliveryMode

Synopsis

sendmail can use four modes for delivering mail. Three have always been a part of sendmail: background, interactive, and queue-only. The deferred mode has been added under V8.7 and later sendmail.

The mode is selected with the DeliveryMode option:

O DeliveryMode=mode             configuration file (V8.7 and later) 
-ODeliveryMode=mode             command line (V8.7 and later) 
define(`confDELIVERY_MODE',mode)    mc configuration (V8.7 and later) 
Odmode                          configuration file (deprecated) 
-odmode command line (deprecated) 

The mode argument is of type character. It is case-sensitive (must be lowercase) and is selected from one of the keywords shown in Table 24-16. Only the first letter of each is recognized, but we recommend full words for improved clarity.

If the entire DeliveryMode option is missing, V8 sendmail defaults to background mode, but old sendmail behaves unpredictably; consequently, this option should be considered mandatory. The default for the mc configuration is also background.

If the mode character is anything other than the first lowercase ...
