Sorry I wasn't more clear. I was referring to the fact that the directory would be openly publishing a list of everyone's email addresses. Even if you hash them, they're pretty trivially invertible. I don't know much about the state of the art of spam filtering these days, so it might be that this isn't a problem, but it doesn't seem great. - moxie -- http://www.thoughtcrime.org _______________________________________________ Messaging mailing list [email protected] https://moderncrypto.org/mailman/listinfo/messaging
