LSUMail: Banned Attachment Types

There may be broken links in this article, the GROK staff has been notified and is working to resolve the issue.


As a proactive measure to fighting new virus outbreaks, LSU blocks e-mail containing attachment types that are commonly used to propagate Internet viruses and worms. None of these attachment types are allowed into our e-mail systems from the Internet, and most of these attachment types are not permitted to be sent within the LSU e-mail systems as well. Anyone attempting to send a message with these attachment types will receive an "E-mail rejected due to attachment" or "5.7.1" error.

Note: ZIP files are now permitted to be sent via e-mail; however, e-mails containing ZIP files will be blocked if the ZIP file contains one of the file types below.
