When multiple envelopes are
processed from the queue and are destined for the same host, only the first will be deferred
and have its number of attempts incremented. The others will not be tried because the host
is unavailable, and therefore will not have their number of attempts incremented. Thus, the
ntries equate shows only actual attempts.

Note that the ntries= syslog equate is shown only for recipient records. Also note that the
ntries= syslog equate will appear only if the LogLevel option (?§24.9.61 on page 1040) is set
to 10 or above.
14.6.17 pri=
The initial priority syslog equate
The pri= syslog equate shows the initial priority assigned to the message (?§25.10 on page
1148). This value is calculated once when the message is first processed and changed each
time the queued file is tried. This pri= syslog equate shows the initial value.
The pri= syslog equate is displayed only for the sender. As of V8.10 sendmail, this equate is
displayed only for the recipient, and it shows the current priority as it changes with each
delivery attempt.
14.6.18 proto=
The protocol used in transmission syslog equate
The $r sendmail macro (?§21.9.82 on page 842) holds as its value the protocol that was used
when a mail message was first received.
