The number of seconds the message spent in the queue.
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.
The same as the difference of timestamps, but calculated by the engine. Convenient because it does not depend on the time format.
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 |
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.
<acct-file /var/log/pmta/acct.csv> record-fields d *, totalSecondsQueued</acct-file>
head -1 "$(ls -t /var/log/pmta/acct-*.csv | head -1)" | tr -d '\r' | tr ',' '\n' | grep -n '^totalSecondsQueued$'
