1. No space between "error:" and the DSN code. error:5.1.2 ... 2. If this system accepts inbound mail to your domains, it may not be able to send back bounce messages to the external sender domains. So generally such transport entries are only for null-client MSAs that punt all mail to "smarthosts". If that describes your system, you're fine. Otherwise, you need a more sophisticated approach. -- Viktor.
