If You Receive Spam

Spam is unsolicited mail. It be in the form of commercial email that you did not request, or it could be some type of Phishing or Masqueraded mail.

If You Receive Spam Messages At Your Non-CS @jhu.edu Account

If you receive email directly at your JHU acct, i.e., your @jhu.edu email address (without it being first forwarded from your CS account to your JHU account), what should you do?
In this case, since you're only dealing with JHU's mail service, you should read: JHU's Reporting Spam and Suspicious Email page for instructions.
Again, this is for those receiving email directly at their @jhu.edu account, and not for those receiving email at their @cs.jhu.edu first and having it forwarded to their @jhu.edu account.
