What is the best C++ Mail library used to read EML file / Outlook MSG file?

Question

We have to develop an in-house mail app. Please let me know what the best CPP library used to read EML file and Outlook MSG file?

Answer 1

EML is basically the same as MHT; it's a plain text format which you can parse yourself, and I believe the WebBrowser control can also display the contents of an EML/MHT.

MSG is a binary MAPI format. You can use the MAPI libraries to deal with these (Windows only). For more information on how to deal with that, see this page.
