ITS has begun enabling new, proactive anti-spam and anti-phishing email filters intended to improve the filtering of unsolicited and unwanted messages, by leveraging external reputation-based lists of email servers that have been flagged for sending spam and/or malicious email.
We’ve had the new filters in “Tag” mode since October 2014, so we’re confident that they are accurate and we’ll be closely monitoring incoming mail queues during days after the change. Still, there is a possibility that someone trying to sending you email will have their message blocked, if their email servers have been flagged for sending spam and/or malicious email. The sender, in such cases, will receive an email advising them that their message could not be delivered.
If you encounter such as scenario, (i.e. a legitimate sender is trying to email you, but the message is being blocked by Middlebury’s email servers), or you have noticed legitimate messages recently having been incorrectly tagged as [SPAM?], please contact the ITS Help Desk at firstname.lastname@example.org and we will help you identify and resolve the issue.
General questions about this change may be directed to email@example.com.
