Thanks guyz.
Two things:
1. Do you really want 2 newlines for each output?
2. Since the first regex is matching the e-mail address and
ONLY the e-mail address, you're actually telling the s/// to
search the entire string for an e-mail address and substitute
the e-mail address with itself, not, as you intend, to substitute
the entire string with itself. You want to add a .* after the closing
parenthesis, maybe.
Instead of: $filestring = s/(\w+\@\w+\.\w+)/\n$1\n/;
Try: $filestring = s/(\w+\@\w+\.\w+).*/\n$1\n/;
Or Possibly: $filestring = s/.*(\w+\@\w+\.\w+).*/\n$1\n/;
Untested, but I had a similar problem recently, and the
principle is the same.

Shawn,
Thanks for your help. But I couldn't use that as well. I am getting
null value for $filestring when I am printing it:
$filestring = <FILE>;
$filestring = s/.*(\w+\@\w+\.\w+).*/$1/;
print $filestring;
Got any suggestion?
Thanks.

Thanks again Shawn, It did work but only printed a part of the last
email in the first line. how do i go about the newline chars in the
$filestring? i am storing the string from the file handle in
$filestring. is this correct?
thanks.

Yeah, just a typo. Replace = with: =~
I didn't catch that in the OP.
