As expected. These are deferred deliveries that ultimately fail when
the queue life time times out. Host unreachable, CNAME lookup failed
temporarily, "no more space of device" permanently, etc.
Success = qmail is done with message. This is successful delivery, or
permanent error. A temporary error becomes permanent at the timeout.
So:
1.75 0.69 90
90% of deliveries get done very fast (probably most are local)
10.33 1.20 98
98% of messages get done very fast, there are some remote ones among
these.
100.18 97.06 99
99% of messages get done ok. There are some slow remote ones among
these.
608402.00 100.41 100
100% takes a long time. The last % contain mainly temporary failures
that ultimately time out.
All as it should be on a very lightly loaded system that does mainly
local work.
