> The bit about "multi-part email" is pure nonsense. No it's not. Emails can have both text and HTML versions, and the email client will decide which one to show in different contexts (e.g. if someone is on a device that can't show formatting and/or image content). Using the text part to include content that is never intended to be rendered as the full email is abuse of this feature. > Having a different from and reply-to is also built into the way email was designed. What you're describing is from being jimmy@ and having reply-to as donate@ But this is not what the article describes. The emails do not have a separate reply-to address. They have a from line which is something like: From: "legitster@legitster.com" <rahim@encona.com> i.e. using the 'name' part of the from header to make it seem like the email is from a different email address.
