I am unable to send an email with one of the following file types attached: .exe .vbs .pif .scr .bat .cmd .com .cpl .dll. Why is this?

These filetypes are blocked, including in archives. This is an additional defence against viruses that our virus scanner may not be able to detect.

You could either send such files “double packed” over a top-level encrypted archive (whereby our scanner won’t recognise them), or you could use a file transfer service (such as Tresorit or Teamdrive).
