If Smiling_Dragons suggestion does not work, you can use the Tie::File module, which allows you to read and write to a file just like a perl array. See the Tie::File documentation for usage details. It's also a core module so you should have it installed already. If you get stuck, post back.

Mail::Box::Tie(3pm)					User Contributed Perl Documentation				       Mail::Box::Tie(3pm)

NAME
Mail::Box::Tie - access an existing message-folder as an array or hash SYNOPSIS
As an array: use Mail::Box::Tie; tie my(@inbox), Mail::Box::Tie::ARRAY => $folder; tie my(@inbox), Mail::Box::Tie => $folder; # deprecated print $inbox[3]; or as hash: tie my(%inbox), Mail::Box::Tie::HASH => $folder; tie my(%inbox), Mail::Box::Tie => $folder; # deprecated print $inbox{'<12379.124879@example.com>'}; DESCRIPTION
The use of "Mail::Box::Tie" is deprecated, because it is succeeded by two separate modules: Mail::Box::Tie::ARRAY and Mail::Box::Tie::HASH. However, this module still works. Folders certainly look like an array of messages, so why not just access them as one? Or, the order is not important, but the message-ids are (give relations): why not access them from a hash based on this message-id? Programs using one of these ties will look simpler than programs using the more traditional method calls. SEE ALSO
This module is part of Mail-Box distribution version 2.105, built on May 07, 2012. Website: http://perl.overmeer.net/mailbox/ LICENSE
