Here's the output from 'smtpd -dv -Tlookup' when using my mobile phone:


debug: smtpd: offline scanning done
93d95e59d30926fa smtp connected address=148.252.132.246 host=<unknown>

93d95e59d30926fa smtp disconnected reason=disconnect


Here's the output when I send on my LAN (same debug command):

debug: looking up pki "mydomain.tld"

93d95e5a86cc1911 smtp tls ciphers=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256

93d95e5a86cc1911 smtp authentication user=pete result=ok
lookup: match "10.1.2.3" as NETADDR in table static:<anyhost> -> true
lookup: match "outlook.com" as DOMAIN in table static:<anydestination> -> true


I don't see the 'lookup: match' lines in the log output when sending from my 
phone for some reason.


Pete.
