Subject [jira] Created: (JAMES-881) ValidSentAddresses not removed from recipients list on SendFailedException
Date Mon, 17 Nov 2008 18:39:44 GMT
ValidSentAddresses not removed from recipients list on SendFailedException
--------------------------------------------------------------------------

                 Key: JAMES-881
                 URL: https://issues.apache.org/jira/browse/JAMES-881
             Project: JAMES Server
          Issue Type: Bug
          Components: Remote Delivery
    Affects Versions: 2.3.1, 2.3.0
            Reporter: Jean Marc


In the deliver() loop of RemoteDelivery, when a SendFailedException is received as a  "452
Too Many Recipients" from a remote server, the processing continues to the next available
server regardless of the ValidSentAddresses, and the whole list of original recipients is
sent again to the next server of the domain, creating multiple duplicate emails in the recipients
accounts.

The typical example is Yahoo, which accepts a variable number of recipients per email from
a specific server according to their internal business rules (bulk settings, SPF, reverse
DNS, etc). For example, Yahoo servers receive a mail for 69 addresses,  accepts the email
for the first 30, then stops processing the mail and returns code=452 and the list of valid
sent/unsent addresses. James logs the list of valid sent, and continues to the next mx record,
sending the email to the 69 recipients again.

Should the code 452 be treated as an error code, or RemoteDelivery remove the validSent from
the list before 'continu'ing to the next server ?
