The Timeout
option is used to set many internal timeouts.
Its general form looks like this:
OTimeout.event
=interval
Here we describe each event. Each interval is represented by an integer followed by a unit of time: s for seconds; m for minutes; h for hours; d for days; and w for weeks. They may be chained, as for example:
3d22h4s
sets an interval of 3 days, 22 hours, and 4 seconds.

of the next anticipated SMTP command

(see §34.8.70.14,
or define one of
confTO_ QUEUERETURN
, confTO_QUEUERETURN_ NONURGENT
,
confTO_QUEUERETURN_NORMAL
, or confTO_QUEUERETURN_URGENT
with the m4 technique).
urgent
|normal
|%non-urgent
]]=intervalCauses a warning to be sent to the sender when a message is still undelivered
