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.
Sets the maximum interval of time to wait for arrival
of the next anticipated SMTP command
(see §34.8.70.1,
or define confTO_COMMAND with the m4 technique).
Sets the maximum interval to wait for the connect(2)
system call to return
(see §34.8.70.2,
or define confTO_CONNECT with the m4 technique).
Sets the maximum interval to wait for
each DATA block read to complete
(see §34.8.70.3,

(see §34.8.70.4,
or define confTO_DATAFINAL with the m4 technique).
Sets the maximum interval to wait for acknowledgment
of the SMTP DATA command
(see §34.8.70.5,

Specifies how long to wait for an NFS-mounted

or define confTO_ FILEOPEN with the m4 technique).
Sets the maximum interval to wait for acknowledgment
of the SMTP HELO or EHLO commands
(see §34.8.70.7,

Specifies the interval for which persistent host status
should be considered still valid
(see §34.8.70.8,
or define confTO_HOSTSTATUS with the m4 technique).
Sets the maximum interval to wait for the
first connect(2) system call to complete
(see §34.8.70.9,
or define confTO_ICONNECT with the m4 technique).

RFC1413 identification protocol to complete
(see §34.8.70.10,

Sets the maximum interval to wait for acknowledgment
of SMTP commands, other than those specifically
mentioned here
(see §34.8.70.13,
or define confTO_MISC with the m4 technique).
urgent|normal|\%non-urgent]]=intervalSets the maximum interval to try to deliver a message. The first time it
fails after this interval, it is bounced.
Three optional keywords can follow to what is bounced.
They correspond to values given in a message's Priority: header.
The literal ".*" is a wildcard that encompasses all three keywords
(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
after this interval. Three optional keywords can follow as described
above
(see §34.8.70.15,
or define one of
confTO_ QUEUEWARN, confTO_QUEUEWARN_NONURGENT,
confTO_QUEUEWARN_NORMAL, or confTO_ QUEUEWARN_URGENT
with the m4 technique).
