Examples are NOOP (which stands for no operation) and VERB (which tells
the other side to enter verbose mode). The time that the local sendmail waits for acknowledgment
of these miscellaneous commands is defined with the misc keyword. Here are the
forms:
O Timeout.misc=timeout ?†? configuration file (V8.6 and later)
-OTimeout.misc=timeout ?†? command line (V8.6 and later)
define(`confTO_MISC??, `timeout??) ?†? mc configuration (V8.6 and later)
The default timeout is two minutes, and no minimum is specified. The mc technique uses
confTO_MISC, for which there is no default.

24.9.119.18 Timeout.queuereturn (V8.7 and later)
This keyword determines a mail message??™s lifetime in the queue. Beginning with V8.7, this
queuereturn keyword is used to set the amount of time a message must wait in the queue
before it is bounced as nondeliverable. It uses these forms:
O Timeout.queuereturn=timeout ?†? configuration file (V8.7 and later)
-OTimeout.queuereturn=timeout ?†? command line (V8.7 and later)
define(`confTO_QUEUERETURN??, `timeout??) ?†? mc configuration (V8.7 and later)
The queuereturn keyword can be further tuned on the basis of three possible levels of
priority that a mail message can have.
