I'm writing a wrapper API to send some email reports to a third-party SaaS which parse them and get some information about them. My users have to report with .eml or .msg file (I am required to accept both formats).
I just found out my SaaS provider does not deal with .msg files, so if I forward a .msg file with my wrapper, it won't be analyzed by them.
I was thinking a possible workaround: since .eml files work just fine, I could convert the .msg into .eml. In this way I can treat both formats as one and my SaaS will produce their reports.
At the moment I used the python library https://pypi.org/project/extract-msg/[extract-msg][1] to try to parse the .msg files, but I didn't found a way to convert it entirely right away.
Also I would like to run this conversion in-memory if possible, without saving the output conversion in a file.
Does Anyone know any library I can use or another way to achieve the result?
