A method for transmitting information (from a source computer to one or more target computers) is proposed. The solution of the invention applies to a message (300o) that includes a main body (310) with possible attachments (315), each one identified by a corresponding internal link (320i) The attachments including bulk data are removed and placed onto a location (125s) of a distribution service wherein they are available for downloading; at the same time, the internal links of the removed attachments are replaced with external links (320e), which point to the corresponding downloading locations. The resulting compacted message (300c) is transmitted to each target computer directly. The target computer downloads the desired removed attachments (from the locations pointed by the corresponding external links); the message can then be reconstructed by restoring the downloaded attachments.
