Not until your dsl connection is back, no. Also, such  command should 
aready be active. During startup a command like:
sendmail -bd -q15m

or for newer releases:

 sendmail_start() {
  if [ -x /usr/sbin/sendmail ]; then
    echo "Starting sendmail MTA daemon:  /usr/sbin/sendmail -L sm-mta 
-bd -q15m"
    /usr/sbin/sendmail -L sm-mta -bd -q15m
    echo "Starting sendmail MSP queue runner:  /usr/sbin/sendmail -L 
sm-msp-queue -Ac -q15m"
    /usr/sbin/sendmail -L sm-msp-queue -Ac -q15m
  fi

The second incarnation is the sendmail queue daemon., which takes care 
of handling queued messages. In this case every 15 minutes.

Without you dsl connection, your DNS does not work, thus sendmail cannot 
deliver. Sendmail is in that aspect totally dependent on DNS.
