The regex what i used to get above o/p
preg_match_all('/(?<=Subject: )(.*?[\n][\s]*?)(?=From:)/is',$content,$rest);
but it does not gives last one as it does not have 'from' to get the middle data. Hope its clear. Please let me know if there are any other method too, for this.
preg_match_all('/(?m:^From:\x20(?<From>[^\n]*)\n^Sent:\x20(?<Sent>[^\n]*)\n^To:\x20(?<To>[^\n]*)\n(?:^Cc:\x20(?<Cc>[^\n]*)\n)?^Subject:\x20(?<Subject>[^\n]*)\n)(?<Body>.*?(?=(?:\nFrom:)|$))/s',$content,$matches);
echo "<pre>".print_r($matches,true);
Its providing the nearly the correct o/p.Should i provide the text file on http://www.mangalsutrabandhan.com
You're going to need some much smarter parsing to make sense of this - whatever produced this file is changing the structure of the emails:

There should be at least one blank line between what appears to be part of an email header and it's body.
Then you've got the problem of top-posting (and you can't rely on the timestamps in the headers without knowing the timezones), incomplete headers and no quoting.
So even if you built a heuristic to parse this, there are too many scenarios that it will not cope with.
