Hi Hugo, Just a heads up in case there was an issue in on sending the email (but I see as well not reserved DLA for it in data/DLA/list).
Two days ago an update for src:libsndfile (1.0.25-9.1+deb8u2) reached the security archive but as per above I think neither a DLA was reserved nor a mail reached the archives. Could you have a look? Regards, Salvatore
