Fix e-mail extract script

I have a script that extracts data from a number (3) of standardized e-mails that requires fixing. The object of the script: - recognize which standard e-mail is received (by sender and by content) - search e-mail for product ID and voucher code - store voucher in database - move e-mail to read folder - send confirmation e-mail (or error e-mail when failed) The current script produces error messages. It has problems with the HTML in the e-mails. Maybe a complete overhaul works best.
