Blocked Email Attachments (Central Email Services)

Due to viruses, e-mail attachments which have the following file extensions are blocked from being delivered to the Central Server Systems RCI and Eden. This list may be updated as more types of viruses are discovered.

.ade    .adp    .bas    .bat    .chm    .cmd    .com    .cpl    .crt    .dll
.emf    .exe    .fxp    .grp    .hlp    .hta    .inf    .ink    .ins    .isp
.js     .jse    .mda    .mdb    .mde    .mdt    .mdw    .mdz    .msc    .msi
.msp    .mst    .ops    .pcd    .pif    .prg    .reg    .scr    .sct    .shb
.shs    .vb     .vbe    .vbs    .wmf    .wsc    .wsf    .wsh

An exception is being made for .emf/.wmf image files contained within Microsoft Office file types (.docx, .xlsx, .pttx). But messages with .emf/.wmf attachments will be blocked.

Someone who sends a message with one of these file types attached will receive the following message:

Our content checker found
    banned name: "[filename.ext]"
in email presumably from you ([e-mail address]), to the following
-> [e-mail address]

Delivery of the email was stopped!

The message has been blocked because it contains a component
(as a MIME part or nested within) with declared name
or MIME type or contents type violating our access policy.

With a little effort it is still possible to send ANY contents
(including viruses) using one of the following methods:

- encrypted using pgp, gpg or other encryption methods;

- wrapped in a password-protected or scrambled container or archive
(e.g.: zip -e, arj -g, arc g, rar -p, or other methods)

Note that if the contents is not intended to be secret, the
encryption key or password may be included in the same message
for recipient's convenience.

We are sorry for inconvenience if the contents was not malicious.

The purpose of these restrictions is to cut the most common propagation
methods used by viruses and other malware. These often exploit automatic
mechanisms and security holes in certain mail readers (Microsoft mail
readers and browsers are a common and easy target). By requiring an
explicit and decisive action from the recipient to decode mail,
the dangers of automatic malware propagation is largely reduced.
