Sending mail via smtp.gmail.com in QT on OSX
-
Hi,
I'm trying to do something that should be quite straightforward.
My application should send an e-mail to a list of addresses. Since it will be a simple message containing some text I thought smtp would be enough to get the job done, and google provides an smtp server (smtp.gmail.com)I based my code on an example I found online which was very helpful.
http://morf.lv/modules.php?name=tutorials&lasit=20When I tested my code everything seemed to go well until I got to the point where the connection was supposed to be made my debug output shows this:
qt.network.ssl: QSslSocket: cannot resolve SSL_set_psk_client_callback qt.network.ssl: QSslSocket: cannot resolve TLSv1_1_client_method qt.network.ssl: QSslSocket: cannot resolve TLSv1_2_client_method qt.network.ssl: QSslSocket: cannot resolve TLSv1_1_server_method qt.network.ssl: QSslSocket: cannot resolve TLSv1_2_server_method qt.network.ssl: QSslSocket: cannot resolve SSL_select_next_proto qt.network.ssl: QSslSocket: cannot resolve SSL_CTX_set_next_proto_select_cb qt.network.ssl: QSslSocket: cannot resolve SSL_get0_next_proto_negotiated stateChanged QAbstractSocket::HostLookupState stateChanged QAbstractSocket::ConnectingState stateChanged QAbstractSocket::ConnectedState Connected error QAbstractSocket::SocketError(13) stateChanged QAbstractSocket::ClosingState stateChanged QAbstractSocket::UnconnectedState disconneted error "The issuer certificate of a locally looked up certificate could not be found"I thought maybe the fault was in my code so I tested the example provided online and got the same issue.
I googled for a while and found out that OSX has some issues with OpenSSL, and that's why the connection can't be made.
I have absolutely no experience with SSL or anything like it so I was wondering if anyone could tell me how to work around this issue on mac.
Any help would be much appreciated.

Hi,

Thank you very much, I used the work-around they proposed
(storing a copy of the certificate in the local resources of the app & adding that to the default CACertificate list before opening the socket)
I'm afraid this won't be a clean long term solution though (the certificate will stay valid for a while, but eventually expires I guess).
If anyone has any idea's for a more clean/permanent solution I'm very much open to suggestions.
In the mean time this will have to do.
Thanks again, I appreciate the comment
