Thanks Chris,

Putting it in the router would be great for me, but I already have a
condition in each and I'm not sure if I can specify multiple condition
lines per router?

I agree that something could go wrong with the transport and the message
would fail but still be logged as a success. It's also data feedback
from the transport that I really need like 'I wrote that message to
file /foo/bar/hum' or 'I got a 250 from the destination server'.

This information mostly gets written to the logs, but I don't think it's
available during the life of a message to 'use' in my concept.
