As a security measure, files with the following extensions cannot be sent via E-mail:

� ZIP
� EXE
� SCR
� COM
� PIF
� BAT
� CMD
� EML
� LNK
� VBS
� MP3

As a workaround, you can rename these files. Explain in the E-mail that they need to rename them after receiving them, and let the people know verbally that they should expect that file.

For example: You create a large file and decide to Zip it. It gets saved as UNHCE.ZIP. Rename it to UNHCE.TIP, and say in the body of the E-mail that they need to rename the file to UNHCE.ZIP in order to open it properly.

NEVER open a file with a suspicious extension, unless you are expecting to receive it. Even trusted sources, such as fellow UNHCE staff members, can get infected computers which automatically send out viruses or worms.
