Can people use my CipherSend account to send me spam?
Unlike unprotected email addresses, the CipherSend server requires that a “spam protection code” be entered with every single message that comes through. That doesn’t ensure that someone can’t “spam” you with an unsolicited advertisement, but they will have to be patient enough to send their spam one message at a time to every recipient – not a likely or profitable endeavor for most spammers.
