SafeMIMEText

This class provides a secure implementation of MIMEText that prevents header injection by forbidding multi-line headers. It automatically manages payload encoding, specifically handling long lines in UTF-8 content by applying Quoted-Printable encoding to ensure compliance with RFC 5322 line length limits.

Attributes

Attribute	Type	Description
encoding	string or Charset	The character set used to encode the email content and headers, typically passed during initialization.

set_payload()

@classmethod
def set_payload(
    payload: string,
    charset: string = null
) - > null

Sets the content of the email message and automatically selects an appropriate transfer encoding to handle long lines if UTF-8 is used.

Parameters

Name	Type	Description
payload	string	The actual text content or body to be stored in the email message.
charset	string = null	The character set of the payload; if set to 'utf-8', the method may force Quoted-Printable encoding to ensure RFC 5322 compliance for long lines.

Returns

Type	Description
null	No value is returned.
