i think i confused noone. you (florian pelz) have invalid DKIM signatures (domain pelzflorian.de), while florian pritz has correct signatures (domain xinu.at).
From this I'd think there's a problem with header or body being slightly modified somewhere on the way (added line breaks or something. I think, we've relaxed/relaxed set, so let's see if it
It looks like the problem has something to do with the "canonicalization" scheme used (c=... in the dkim-signature) Florian Pritz is using relaxed/simple and it passes, Florian Pelzs messages fail using simple/simple, the same is true for Georg Schlisio, while Lukas Rose (quit early in the thread) passes using relaxed/relaxed. passes) Ralf Mardorf has DomainKey-Signature with c=nofws, seems to be something else and passes. Giovanni Santini uses dkim with relaxed/relaxed plus some X-Google-DKIM-Signature - and this combination fails with "Body has been altered" (as opposed to "Message has been altered" for the other fails) in amavis. hope that is somehow useful, regards, Gabriel
