Regex help matching 5 lines

I'm looking for some help from a regex guru, here's what I want to be able to match and remove using ruby/rails:

-----Original Message-----

Subject: Ra开发者_StackOverflow社区ndom replied to the comment

is it possible with regex to match these 5 lines with one Regex? Here's what I've been trying, without luck:

gsub(/-----Original Message-----/n.* From.*/n Sent.*/n To.*/n Subject.*/, '')

Thanks for the help

You need to reverse the slashes for the newlines and remove the extra space after each newline.

-----Original Message-----\n.*From.*\nSent.*\nTo.*\nSubject.*
