    Depends on what service your mail is based on.

    • Microsoft Exchange -> The API is proprietary so the only method I know of is using C++/CLI (so the whole .Net framework stuff)

    • SMTP -> libcurl is probably the most popular library

    You can still handle it all manually via QTcpSocket however.

    Honourable mention, even if it's not so popular: https://www.vmime.org/

            To build libcurl you can use CMake

              easiest would be to use a already existing solution.
              like this one - drawback is that it was written for Qt4. So it may not compile for Qt5 without some modifications.... i don't know.
              Or this one for Qt5.

              Worth to check at least.

                      are you creating the socket and it connection?
                      or is this handled internally in the lib?

                            Hi,

                            The best way to know why is to run your application through the debugger, you should get the point where the problem occurs.
