Account email is wrong

If we receive bounced emails to the customer:

•  the email given is either inaccurate (if the email has a common domain such as gmail, yahoo, aol, etc)
• their host provider has our domain blocked (windstream.net, dejazzd.com, PTD.net)
• If they are using any other these, ask if they have another email to try

Go to the customer page for customer and edit their email. If the email already exist, find the customer page for that email, edit the email but changing it from "craig@aol.com" to "c@aol.com" or "craig@aol.co", save and then delete the customer. You can then update the email. 

USE THE ACCOUNT THAT HAS THE ORDER PLACED ON IT. NOT THE EMPTY ACCOUNT WITHOUT ORDERS (which is usually the case)

Then search Vauchar using the old email which was wrong and forward each voucher to the correct email using the "forward email" link found at the bottom of each voucher line
