It seems that no search engine indexed this. I spent a few hours finding what happened. I think the change in openssl version from 1.1.0f-4 should mentionned heavily in the NEWS file. My personal email server cannot receive emails from other servers. Of course, those other servers should be upgraded, but I don't even know how to contact them… Anyway, this patch should be integrated ASAP. At least for my own needs :) In the meantime, I'll wait with a downgraded version of openssl. Have a nice day, Adrien
