We planning to enhance the functionality of TscMailMessage to replace Indy components in your project. To achieve this, implementing a method like SaveToFile and SaveToStream is indeed a practical approach for exporting messages in EML format.

The SaveToFile method would save the email message to a file in the EML format, while the SaveToStream method would store the email message into a stream. These methods could be modeled after similar functionality in the Indy components.

Here's an example implementation outline for both methods:

1. SaveToFile:

   • Accept a file path as an argument.
   • Convert the TscMailMessage object into EML format.
   • Write the formatted message into the file.

2. SaveToStream:

   • Accept a stream object as an argument.
   • Convert the TscMailMessage object into EML format.
   • Write the formatted message into the provided stream.
