I wrote some code to send email as both HTML & Text, and I am having having trouble testing it.
On Thunderbird and Outlook, there is an option to view as plain-text, however I have a feeling that they are being smart and doing something to the plain text (because it looks slightly different in thunderbird than in outlook).
What's the crappiest email client out there? One that simply has no HTML support and would not be smart enough to convert HTML to text by itself.
I'd like to see the worst solution.
