You question this whole feature, its very nature.

Spammers don't need Thunderbird, they have specialized tools. And spammers already do this in billions. This feature might actually help educating users how easy it is to forge email addresses, and to be more careful when they see From: <email address hidden> "Please update your address".

* If you really want to pref this feature away, I think the best way would be a checkbox in "Account Settings..." | "Manage Identities...".
* If we insist that only one account can have this checkbox checked, it would solve the "which SMTP server" question
* But it would make this feature very obscure and hard to find.
