When SMTP client is trying to login by using SMTP AUTH (LOGIN scheme) and the server answers a 4xx error code (saying "server temporary down"), the mail client is trying to log in again immediatly without notifying the problem to the user. The best would be to retry later... The bug is in the nsSmtpProtocol::AuthLoginResponse function because you don't take care of the 4xx error code (only 2xx, 3xx and 5xx)
The problem seems to be fixed with later version of Mozilla and Thunderbird.
