Read .eml files

Rails
1

Hi there,

I have .eml files stored in filesystem and would like to read them and
present to user. What can I use?

I tried GitHub - mikel/mail at 2.2.7 but when I perform
Mail.read(‘filename’) i get: NoMethodError: undefined method `read’
for #Class:0x9663290

Regards,
Mateusz
