The name of the account under which authentication took place.
It is not written by default — the field has to be named in record-fields. The field set is defined in the accounting block, and fields are worth adding deliberately: there are as many delivery records as delivered recipients, and every extra column is multiplied by that volume.
Here a login is created for each sending pair, plus one more — the shared pool login: this field shows which of them submitted the message.
Where the field exists and whether the star includes it:
| Record type | In the star |
|---|---|
| d — delivery | no |
| b — bounce | no |
| t — temporary failure | no |
| r — reception | no |
In a shared file an empty value comes in two kinds: the line has no data — or the field is not selected for its record type.
