-t
Get recipients from message header All versions
The -t command-line
switch causes sendmail to
gather its list of recipients from the message’s
header in addition to gathering them from its
command line. The -t switch takes no arguments.
When this switch is specified,
sendmail gathers recipient
names from the To:, Cc:, and Bcc: header lines. It also gathers
recipient names from its command line if any were
listed. Duplicates are discarded, the Bcc: header is stripped,
and the message is delivered.
The -t switch is
intended for use by MUAs. It should
never be specified when
sendmail is run in daemon
mode.
