Mail Statuses

Each mail in the Bounced Mail Framework (BMF) is assigned to a status.

The status is determined by the following factors:

  • Has the mail time limit for a response been exceeded?
  • Is there a response?
  • Is the client application processing successful?
  • Is the BMF mapping using patterns successful?
  • Has a rejection reason been identified?

To understand how mail statuses are resolved, you must be familiar with the basic BMF principles.

Key to Factors:

TLE - Time Limit Exceeded

RES - Response from External System

SCAP - Successful Client Application Processing

SM - Successful Mapping

RRI - Rejection Reason Identified

(LIS)

Each sent mail has a value, called TTR (Time-to-Respond). When the specified period of time passes and there is still no response, the mail status changes to LIS.

All responses received after the time limit is exceeded are ignored.

Valid

There is a response, the mapping and the client application processing were successful and no rejection reason has been found, so the mail has the status Valid.

These mails are automatically transferred to Statistics.

Bounced

There is a response and the mapping is successful, but the client application processing is not successful.

The BMF has found a rejection reason, so the mail has the status Bounced.

Depending on the reason, the bouncing can be:

  • Hard bounced (Suspended) - these bounces indicate permanent problems, for example, if the e-mail address does not exist. The BMF suspends addresses with hard bounces and no more mails are sent to them.
  • Soft bounced - these bounces indicate temporary problems, for example, if the server or user quota is exceeded. A soft-bounced mail can be resent but only a limited number of times. If the limit of resending tries is reached, the mail address is hard-bounced.

Unrecognized

The following reasons cause a mail to be set to the status Unrecognized:

  • The client application processing is not successful and the rejection reason cannot be identified.
  • The mapping is not successful, so the BMF cannot identify the client application to which the incoming mail belongs.
  • The mail is valid but a rejection reason has been found.
