Cross Platform C++ IMAP Library

Question

Are there any cross-platform (only interested in Windows and OS X) IMAP libraries which I can use from C++? Preferably open source as well.

I am currently using the IMAP library from Chilkat, but this is Windows only.

I've found libEtPan and VMime and just wondered if there were any others I could look at to compare.

Answer 1

What about VMIME?

It has all my favorite things in a library:

1. Free, as in free beer
2. Free, as in free speech (Open Source also)
3. Regularly updated (very important)
4. Decent (though not great) documentation
5. Portable

Answer 2

Although a bit dated since it's development has stopped being open-source, you can check the UW-IMAP toolkit. However, its primary author continues development of the toolkit under the name Panda-IMAP and makes it available to anyone who wishes to donate for the development of the project.
