My postfix installation does not log most of the messages after changing myhostname. The myhostname is now different from the FQDN (and hostname) of the machine where it used to be the same. After changing this (for other reasons) the logging to syslog stopped working for the delivery and queing part. Only some warnings are logged.
When i set the maillog_file parameter all the logging appears there as expected and works as before the name change. There is however 1 thing i notice: in the log-line i see the myhostname in stead of the machine hostname.
I am using rsyslogd on debian with an (for mail) unmodified configuration.
What am i missing? I would like it back to use full syslog logging for obvious reasons....
