This module was written to force the mass mailing module to build `Return-Path` header with a plus sign as technical email separator instead of a dash.
This transformation is mandatory for mails servers that treat the dash as a valid email account character (as in `willem-alexander@koninkrijk.nl`) instead of a technical escape character allowing to add optional parameters to the real email account (as in `catchall-bounces-543-kremlin@vladimir-putin.ru`).
