TCS E-Mail Node Client


---

This document describes the client module for the TCS e-mail service.
It is designed to simplify the requests to the service and provides a usable and expendable interface to integrate the service as easy as possible.


###Note:

- Regular mail attachments to mails are not possible because the mails will be signed via the DomainKeys Identified Mail (DKIM) Standard.
- Images within the html need to be defined as link. Base64 images via styles are not valid.
