Is there any 'source' or does someone have an overview of exactly what priority settings do, and in what order??
I have seen that you can set 'priority' for a domain ZZZZZ to go out of  gateway YYYYY; then there is also some message priorities being reset....

 

Any general overviews or best practice would be greatly appreciated.

 

Just FYI... is we are planning to set-up servers, that specifically outbound email servers.
 

Thanks in advance.
