@1ll173r47 @FediFollows @protonmail @Fairphone @seven So the msg would get past her email firewall but not the realtime scanner. If she needed to go a step further (not sure why), she probably could have gotten a sitewide PGP tool, which would do all the crypto/decrypto outside of the MUA as a builtin feature of her mail server of sorts, in which case the MUA doesn't even know crypto is involved. Then the email fw could intervene.
