grep/egrep use regex expressions for pattern matchine. In your example, try this:

# note the use of -i to force grep to be case-insensitive
# also not the use of single quotes so the shell doesn't expand the wild-cards
grep -i 'delivery of nonspam' mail | grep -i 'to .*#harper' | less

You rock! I was wondering why regex didn't work with double quotations. Tons of thanks!
