[Zope-dev] What to do when one mail recipient fails out of several?

[Trevor Toenjes]

I like the idea of having this capability.
Having the option to integrate it into sendmail or as a standalone scrubber
would be ideal.  Could this become a product?

Next week I get a new list of 500 emails that has never been tested. I would
like to do an SMTP handshake(without sending) to verify the
domains/addresses that will accept the emails, and remove the addresses that
fail.  This makes bounce management much cleaner and lowers overhead when
you actually send the messages.
