Where the attempt ended
The stage of the delivery at which this attempt finished — the first half of MailerQ's failure classification.
In detail
Twenty-four values, from dns before a connection exists to message after the body has been sent. Paired with result, it is the whole classification: dns/error is a domain with no mail server, rcptto/error a rejected recipient, data/timeout a receiver that went quiet after the body. The full list, and what each means for analytics, is in MQ5-delivery-states.
