Outgoing Email Rejections - Please read

Author: sundeep
Event Date: August 15, 2019
Time: 8AM
Affected Groups: Users of ECN mail (Not the campus Exchange/Office365 server)
Type of Outage: Software
Contact Phone: 44326
Campus Group: ECN
ECN SMTP server blacklisted



An account was compromised yesterday, and sent out massive amounts of spam before we were able to turn it off and clean up.
Our current suggestion for anyone seeing mail sending issues is to use the following settings for their SMTP – ESPECIALLY if email is being sent out in the form @purdue.edu (as opposed to @ecn.purdue.edu)
Server: smtp.purdue.edu
Port: 587
Security: STARTTLS
In addition, you may need to
  - change your email address to your @purdue.edu (remove the @ecn if it exists)
  - turn on the VPN (optional step)
Sorry for the inconvenience!
