Here we have a pretty generic email claiming that you can get a “webmaster account upgrade” in order to increase your inbox storage capacity. Note the clunky wording, which doesn’t make any reference at all to UD or Google Apps. The link provided is definitely not a UDel address, and the phisher didn’t even bother trying to disguise it at all. The email is also signed with the vague label “HelpDesk ITS” rather then UD anything.
It’s a pretty standard procedure: the phishers attempt to redirect people to an outside site so they can harvest email login information when unsuspecting victims “sign up” for their service.
Remember to report and delete phishing emails like this one.
