Raw emails required for testing

Question

I play with the new C # digital library and would like to test it as much as possible. I used several POP3 mail servers (e.g. Exchange, Hotmail, Gmail, etc.) to test support for the most popular email MIME formats, for example. text / plain, multipart / alternative, etc.

Does anyone know if there is a test mail repository that I can use to further check for more obscure MIME formats, for example. application / pkcs7 etc.

This is to ensure that the library is reliable enough to handle these types of letters. Thank.
