Steps to reproduce:
My ISP has overloaded servers at times. Sometimes when I try to SMTP-send an email, I get a Thunderbird popup "An error occurred while sending email. The mail server sent an incorrect greeting: Too many concurrent SMTP connections; please try again later." The cause is not me or TB doing too many concurrent SMTPs, but rather to many SMTP connections from assorted users into the shared email server.
Actual results:
However, when this happens, TB acts as though it's successfully sent this email (even though it hasn't been sent), moving the email into the Sent folder. I still have to close the popup dialog manually. But this is misleading--the email has not been successfully sent anywhere.
Expected results:
The email should instead be put into the Drafts folder, or some other folder(?) to indicate that the email has not been successfully sent. And ideally TB should queue up the message and try again later when another Send attempt occurs (forever? N-times?).

Good thing is that you're not losing the e-mail since we have cases where the draft/composed message is lost completely.
Actually, this is a duplicate of bug 780124.
