Spam Filter

General Information

OCMail collects mail messages that it thinks are SPAM in the folder called SPAM. If you forward mail from the current Oberlin Mail server; some messages may get sent to the SPAM folder even though they were processed by the Oberlin College Spam filter.

What should I do if a message is improperly marked as spam?

In the OCMail web interface: Use the 'Not Spam' button to unmark mail that's been misclassified. Just open 'Spam,' check the box next to the message that isn't spam, and click 'Not Spam' along the top. You'll also see the 'Not Spam' button at the top of spam messages you've opened, so you can unmark messages from Conversation View, too. Unmarking messages moves them to your inbox.

Make sure to check your spam folder frequently, especially while your account is new, to train OCMail to recognize the correct messages quickly. Listserv messages have a tendency to get caught in the filter at the beginning, so if you subscribe to a list, make sure your messages are getting through.
