An approach is described of facilitating processing of a message at a target endpoint. The approach may facilitate message processing regardless of format. A method pertaining to such approach may include receiving, at a target endpoint, a message that includes a content portion and a script code portion that is required to execute the content portion. The message may be propagated via a network. The method further may include parsing the script code portion to identify at least one instruction. The method further may include processing the content portion by executing the at least one instruction via at least one scripting engine. The at least one scripting engine may be located in a restricted operating system environment within a virtual machine. According to an embodiment, the script code portion may be stored in a header of the message.
