Doing it in a general, reliable way with bash alone would be very
difficult, but if it's a local server that always responds fast or not
at all, you could try something like this:

#! /bin/bash
case "$( (sleep 5; echo quit) | telnet  192.168.0.20 25 2>&- )" in
  *'
220 '*) echo Success ;;
  *)    echo Failed ;;
esac
