SafeMIMEMultipart

This class provides a secure implementation of multipart MIME messages by extending standard functionality with header validation. It ensures that all headers are processed to prevent multi-line injection attacks while maintaining compatibility with specified character encodings. The class inherits from both MIMEMixin and MIMEMultipart to support complex email structures with enhanced safety constraints.

Attributes
