(sorry for the delay in filing on redmine I had some
problems with creating the account; as said, I'm messing
with SMTP daemons ;) )

Ruby's Net::SMTP quits when the first Unknown User is
encountered. I think Net::SMTP should continue with
other RCPTs, then use DATA to let the mail be delivered
to existing users.

I think this should be so, because

• RFC821 mentions clearly in the second paragraph in section 2
  "if not, it responds with a reply rejecting that recipient
  (but not the whole mail transaction)", and
• RFC2821 leaves this in the middle, but still gives
  an example in section D.1 A Typical SMTP Transaction Scenario
  "C: RCPT TO:[e-mail]
  S: 250 OK
  C: RCPT TO:[e-mail]
  S: 550 No such user here
  C: RCPT TO:[e-mail]
  S: 250 OK"

So, I wrote code to accomplish this.
Please find a patch attached.

Comments welcome, especially on the Errors constructed and returned.
They are in plain text; I can imagine making the unknown and ok
users explicit (arrays within the exception), so that code that uses
Net::SMTP has an easier time determining which emails were not sent.

Bye,
Kero.

PS: patch applies to both ruby_1_8 branch and trunk

There is a typo in this -- line 842 of lib/net/smtp.rb should reference "ok_users" not "ok_addrs"
