At IU, how can I send email with a blocked attachment type?

Since UITS has enabled virus filters for email attachments at IU, you will need to rename the file extension of blocked file types to allow legitimate attachments to be delivered. For a list of typically blocked attachments, see At IU, what types of attachments are blocked from my email account?

If you're sending multiple files, consider archiving them with a utility such as WinZip to prevent email providers from automatically adding them to a zip archive, and thus blocking the message. This way, you can remove or change the file extension and allow the attachments to be delivered. For more, refer to the relevant section below.

Windows 7, Vista, and XP

Windows 7, Vista, and XP have built-in support for zip files, so you can archive and unpack a file or group of files. You'll be able to email this archive as long as you rename the file extension(s) of its contents and then archive it:

1. Make sure Hide file extensions for known file types is unchecked; to change this option, see In Windows or Mac OS X, how do I reveal file extensions?
   
   
2. Right-click each file and then select Rename. Change the last three letters to a file extension not blocked by the attachment filter (e.g., txt), or remove the extension altogether.
   
   
3. Right-click the file or selection of files, and select Add to zip.
   
   
4. Right-click the resulting archive and select Rename. Change the last three letters to a file extension not blocked by the attachment filter (e.g.,txt), or remove the extension altogether.
   
   
5. Attach this file to the message, instructing the recipient to add the original file extension(s).

Mac OS and Mac OS X

1. Rename the file(s) to a file extension that is not blocked by the attachment filters (e.g., txt), or remove the extension altogether; see In Mac OS X, how do I rename a file, folder, or volume?
   
   
2. Create a zip file. See In Mac OS X, how do I compress or decompress files?
   
   
3. Rename the resulting archive to a file extension that is not blocked by the attachment filters (e.g., txt), or remove the extension altogether; see In Mac OS X, how do I rename a file, folder, or volume?
   
   
4. Attach this file to the message, instructing the recipient to add the original file extension(s).
