Update January 2008: the .eml attachment type has been removed from the list below
To limit the propagation of viruses through e-mail, it will no longer be possible to send e-mail to and from VUB/ULB e-mail addresses containing Windows executable attachments as of 15 February 2005.
The newest generation of e-mail viruses have become much more aggressive, more difficult to clean up, and require a great amount of time from VUB/ULB staff members and students to clean up infected computers.
Therefore, as of 15 February 2005, it will no longer be possible to send e-mail messages to and from VUB/ULB e-mail addresses with Windows executable programs in attachment, such as .COM,.BAT,.PIF,.HTA,.EXE,.CPL and others (see below for the complete listing). These files are the most common format used to propagate computer viruses by e-mail and are in most cases of no use to most users.
Attachment types used by popular Windows applications such as .DOC (Word), .XLS (Excel), .PPS and .PPT (Powerpoint) as well as the popular .ZIP will continue to be accepted.
We do remind users that there are a number of viruses using the .ZIP format - protected with a password or not - to propagate, but we count on the receiver not to open suspiciously looking e-mails and their attachments.
Identical measures have been taken by other renowned academic institutions and companies who, like the VUB/ULB, wish to react pro-actively on e-mail virus issues.
