Updating destination list delivery server has failed

24 Dec

This status code should be used when the per-mailbox message length limit is less than the general system limit. This is useful only as a persistent transient error.The host on which the mailbox is resident is not accepting messages.The security or policy status codes report failures involving policies such as per-recipient or per-host filtering and cryptographic operations.

The inability to connect to an Internet DNS server is one example of the directory server failure error.

The message was considered too old by the rejecting system, either because it remained on that host too long or because the time-to-live value specified by the sender of the message was exceeded.

If possible, the code for the actual problem found when delivery was attempted should be returned rather than this code.

Mail system status indicates that something having to do with the destination system has caused this DSN.

System issues are assumed to be under the general control of the destination system administrator.
