How to set multiple servers

I want to use 2 servers one for headers only and the other for
articles only I set this using server mode for each

For the first server (headers only) it works but the second server
(articles only) doesn't attempt to download articles using
message-id's retrieved by the first, is there something elsewhere to set ?

I see in the guide the possibility to export/import nzb file but it
doen't work too even I check "Try downloading by message Ids..."

Any idea ?
