Trying to understand the smtp protocol with multiple recipients. From
what I understand the recipients are specified as follows:
rcpt to:[email protected]

250 Accepted
rcpt to:[email protected]
250 Accepted
Suppose I'm doing forward callouts to verify recipients. And suppose
[email protected] is a bad email address. How should the server respond
to say that there is one bad address but 2 are ok?
What I'm trying to do is pass the email for the good recipients and
reject the email for the bad recipients at SMTP time.
Thanks in advance.

- just as an acceptance code is returned for each accepted recipient,
so, too a rejection code is returned for each one that is unwanted.
- as with any other rejection, it may be temporary or permanent.
Either way... at final rejection ELSE retry timeout, submitting MTA
generates a DSN to the sender so advising. Well 'real' MTA do. Dunno
about the 'bots. Or care.

What I'm finding is that if I issue a DENY then every one after that is
also denied. Unless I'm doing something else wrong.
