Austin Exchange Messaging Service

Banned File Attachments

To protect Austin Exchange Messaging Service (AEMS) users from viruses, worms, and other malware, the AEMS email server blocks and quarantines certain file types that are commonly used to propagate such malicious code. These files are removed from the message and replaced with a notification that is sent to the intended recipient of the file.

Banned file extensions include .at, .bat, .chm, .cmd, .com, .cpl, .exe, .js, .lnk, .pif, .rar, .scr, .shs, .vb, and .vbs.

ITS recommends using UTBox if you need to share files with these extensions. UTBox is also useful for easily sharing large files such as .zip files, which are not blocked.

If you receive a notice about a specific quarantined file that you feel is legitimate, please contact the ITS Help and Service Desk to request that the file be released. Such requests will be handled on an individual basis.
