I'm not quite sure I understand what you are doing, but if you are putting the FULL email message of the returned messages into this text file then I can make a suggestion. If you are just interested in getting the "To:" field of each message then run a grep on the file first using exec() or similar function. That should return a much smaller list of items that can be further parsed inside of the PHP script.

If the only thing in your text file is email addresses.... then I'm not too sure. Hopefully someone else can make a suggestion.
