zope.sendmail also does not handle these events gracefully:
o SMTP Error 45x - temporary error
o Temporary failure to connect() to the MTA to start delivery of a message
o Failure of SMTP TCP connection during SMTP session
I am just finishing writing code that will handle all this gracefully, I will add the SMTPRecipientsRefused Exception handling to it as well.
