Syslog is a hard library dependency for Postfix. Why can't dockerd
provide a syslog forwarder, just like it already provides a stdout
and stderr forwarder? That would also help with other daemons that
rely on syslog to avoid app-specific logfiles.
Options:
- Configure the syslog library destination, if your syslog
library has such an option.
- Link Postfix with a syslog library that can be configured to send
to a different destination.
- Configure a local syslog server to forward the logging without
writing it to file.

Stdout/stderr logging may not be a good idea for a production mail
server. How would one separate records that are written concurrently?
Note that stderr is not buffered, i.e. one byte per write(2) call.
