OK, I'm embarrassed to say this out loud, but I've been administering Linux mail systems for many years and for the life of me I can't figure out what is meant by "Sort By" [1-10] when configuring SMTP transport rules in ISPConfig 3.2.2. I've been configuring systems using shell scripts and I'm new to ISPConfig but I just can't seem to put "Sort" and "SMTP transport" into the same sentence. Any pointers would be greatly appreciated.
Postfix will process all routing rules from top to bottom and use the first one that applies and will stop then. If you have multiple routing rules that might match a certain situation, you can define the order with this field. A higher number means a higher priority, i.e., if you have two rules that apply, and the first has a priority of 8 and the second a priority of 5, then the first rule will be used by Postfix.
