[syslog-ng] Selective application of keep-hostname()?

[Steve Bernacki]

I have a use case where I need to selectively apply keep-hostname(yes) 
to messages from certain source IPs, while defaulting to 
keep-hostname(no) for the rest of my sources. I know I can apply this 
option on a per-source basis, but in this case I want to be able to 
selectively apply this option based on the source IP of the message. I'm 
trying to avoid having to set up an alternate port if I can.

Thanks
Steve
