Error mail from


I got the mail below from my box, just after a bunch of certificate were succesfully renewed. (and some were not since “The certificate is valid for at least another 30 days — no need to replace”.)
Everything seem to be in order,
Status page is all green (except that I am still on 0.21b), mail are going in and out.

Any idea what may be wrong ?
