Theseare perhaps a result of some domains hosted by outlook.com, but not
included in your list of domains to route to the dedicated transports.
You might consider using one of the 4 four transports with the (long
ago up-thread) suggestion to:
main.cf:
...
smtpd_recipient_restrictions =
check_recipient_mx_access <sometable>
<sometable>
# insert all relevant MX host domains here
.outlook.com FILTER transport4
.hotmail.com FILTER transport4
...
and using the other 3 round-robin for the *known* domains, but *raising*
the concurrency limits from 2 to 5 or so, because you now are no longer
competing on the same IPs with the messages that sneak by the static
tables.
