Is any other campus just getting slammed with phishing e-mails? Specifically e-mails that say: "You have exceeded the size of your mailbox please login here to request a size increase".
We haven't seen an increase in it, but we did end up just disabling OWA about a year or so ago because of the rate at which accounts got compromised. It was truly ridiculous.
Also, if you wouldn't mind, could you share with me the products and/or methods you use to "rate limit" user outbound e-mails. Meaning......jdoe () somecollege edu can only send out 100 e-mails per hour.
We're working on a postfix policyd rule to handle this as our Exchange server uses our Linux MTAs as smarthosts, I can share information on that if/when we get it working. -- Nick Kartsioukas Cuesta College Computer Services 805-546-3248
