Sorry to correct you, vino, but your code will work only in most cases, not in all: if the WordToKeep is the last word in the line it will fail because you require a space after it.
On the first line your code will work, on the second it will fail:
It will also fail in cases where the WordToKeep is followed by some punctuation mark like it is the case in texts:
I therefore suggest the following enhancement to your code (<spc> and <tab> are characters, only encoded here for readability):

Email::Folder::Mbox(3pm) User Contributed Perl Documentation Email::Folder::Mbox(3pm)NAME
Email::Folder::Mbox - reads raw RFC822 mails from an mbox file
SYNOPSIS
This isa Email::Folder::Reader - read about its API there.
DESCRIPTION
Does exactly what it says on the tin - fetches raw RFC822 mails from an mbox.
The mbox format is described at http://www.qmail.org/man/man5/mbox.html
We attempt to read an mbox as through it's the mboxcl2 variant, falling back to regular mbox mode if there is no "Content-Length" header to
be found.
OPTIONS
The new constructor takes extra options.
"eol"
This indicates what the line-ending style is to be. The default is "
", but for handling files with mac line-endings you would want
to specify "eol => "x0d""
"jwz_From_"
The value is taken as a boolean that governs what is used match as a message seperator.
If false we use the mutt style
/^From S+s+(?:Mon|Tue|Wed|Thu|Fri|Sat|Sun)/
/^From (?:Mon|Tue|Wed|Thu|Fri|Sat|Sun)/;
If true we use
/^From /
In deference to this extract from <http://www.jwz.org/doc/content-length.html>
Essentially the only safe way to parse that file format is to
consider all lines which begin with the characters ``From ''
(From-space), which are preceded by a blank line or
beginning-of-file, to be the division between messages. That is, the
delimiter is "
From .*
" except for the very first message in the
file, where it is "^From .*
".
Some people will tell you that you should do stricter parsing on
those lines: check for user names and dates and so on. They are
wrong. The random crap that has traditionally been dumped into that
line is without bound; comparing the first five characters is the
only safe and portable thing to do. Usually, but not always, the next
token on the line after ``From '' will be a user-id, or email
address, or UUCP path, and usually the next thing on the line will be
a date specification, in some format, and usually there's nothing
after that. But you can't rely on any of this.
Defaults to false.
"seek_to"
Seek to an offset when opening the mbox. When used in combination with ->tell you may be able to resume reading, with a trailing wind.
"tell"
This returns the current filehandle position in the mbox.
