Administrators: Preventing Spam

Section 1

Occasionally, spammers will attempt to spam your mailing list with a large volume of subscription requests. To prevent this, mailing list administrators can configure their list to require a valid (uci.edu) email address before they can submit a subscription request.

Enter the following "regular expression" into the "List of addresses which are banned from membership in this mailing list." field: 


Find 'list of addresses which are banned from membership' field  

The regular expression will tell the mailining list to check for valid domains before users can make a subscription request. Be sure to click 'Save' at the bottom of the page to ensure that your new changes take place.
