Bad interpretation of the man page. After checking examples, I think it would be like so: bar.net smtp:[smtp.abc.bar.net] Or does it need to be: bar.net relay:[smtp.abc.bar.net] What's the underlying difference between the effect of transport keywords "relay" and "smtp"? Is there technically a difference between the relay and smtp protocols? Thank you, Scott Stirling AT&T, Boston
