I am trying to trace some mails which seems to have gone lost in my system. I have postfix claiming that they where delivered OK:
relay=127.0.0.1[127.0.0.1]:2003, ..... status=sent (250 2.1.5 firstname.lastname@example.org Ok)
I have used grep all of /var/log/kopano/*.log but not found anything usefull. Which log file is supposed to contain whatever action Kopano took on a specific message? And is there a option for extended logging I maybe could give further information?
