[syslog-ng] encrypt syslog-ng messages

[shaun.hofer at altcall.com]

I've setup syslog-ng on a log server and it's successfully receiving log
messages from various clients. I want to encrypt the messages, so I used
SSH tunnels and stunnel. However, in both of those cases, syslog-ng sees
the message as having originated from itself, rather than from the real
sender. Is there a way to fix this, or is there a different way to encrypt
the messages?

Thanks for your help, syslog-ng's awesome.
