Beginning withV8.13, it is possible to set a separate wait for DSN (bounce) messages using
the dsn keyword. One handy use for this would be to prevent warnings from being sent for
DSN mail. You can do this by setting the warning timeout to be greater than the return
timeout for regular mail:

define(`confTO_QUEUERETURN??, `5d??)
define(`confTO_QUEUEWARN_DSN??, `7d??)
Here, normal mail will be returned (bounced) after five days, but because DSN mail won??™t
issue a warning until after seven days, no warnings will be sent.
24.9.119.20 Timeout.quit (V8.6 and later)
When the local sendmail is finished and wishes to break the connection, it sends the SMTP
QUIT command:
QUIT
The other side acknowledges, and the connection is terminated:
221 2.0.0 there.dc.gov delivering mail
The time the local sendmail waits for acknowledgment of the QUIT command is defined
with the quit keyword, the forms of which are as follows:
O Timeout.quit=timeout ?†? configuration file (V8.6 and later)
-OTimeout.quit=timeout ?†? command line (V8.6 and later)
define(`confTO_QUIT??, `timeout??) ?†? mc configuration (V8.6 and later)
The default timeout is two minutes, and no minimum is specified.
