computer says no
In today's edition of "Computer Says No":
I learned that gmail doesn't allow attachments that end in .js (among other blocked file extensions). Instead, it responds to thunderbird with a message that triggers an unhelpful "unknown error" message indicating that the mail was not sent. Despite this, the mail is still copied to my account's "sent" folder.
The problem is more obvious from gmail's web client where they at least display a patronizing "this is to protect you" message.
