Well, let's check...
If you already suspected that it's not the LETU Help Desk, you'd be right.
The “From” line indicates it’s not an LETU.edu address (we always send from letu.edu email addresses)
The link they provide in the email is not an letu.edu address (we typically send you all IT-related links in the form of an letu.edu address)
Nice catch. Being able to identify the elements in a suspicious email or web page will go a long way towards keeping you (and LETU) protected online.
