I have a generic email account set up that emails PDF copies of invoices to customers. One customer is receiving the PDF in a garbled format. If I open the email account that sent the PDF and forward using my email, the PDF comes through ok. It leads me to think the issue is on their end, but they are receiving PDF's from others without problem. I think it may be a setting issue where my email is set up differently than the generic email account, but don't know what setting that would be. I'm on version 6.5.
