The -T command-line
switch causes sendmail to set the
QueueTimeout option (QueueTimeout)
to the value specified. This -T command-line
switch is deprecated (as is the QueueTimeout
option) in favor of the Timeout option of V8.7
sendmail (Timeout), and
might not be included in future versions of
sendmail. Note that -oT is
still a legal form of shorthand to set the value of the
QueueTimeout option.
