The newer dialback spec - XEP-0220 - does include error support,  
which'd allow you to hand the server a textual error reason for  
failure when you reject a <db:result/>, as well as machine-readable  
error conditions.

Would that help admins get a diagnosis of why the dialback is failing  
(in common cases) without you having to manually chase up each case?

If there's anything we could do on a protocol/standards front to make  
self-diagnosis of S2S failure easier, I'd be willing to push for  
that. (And in my guise as M-Link guy, make sure we implement it).
