I would like to sent more emails in one shot... how to do?

Thanks for the great utility. I downloaded it and just added a simple option for Cc. Just think it would be a good addition for anyone else looking for something like this.

body text do not send, need to use message.append("Subject: " + subject + "\n\n");

Trying to send email in different fonts but failed to send it send only plain text.

I open text/html in code but still failed.

Please help.

First off, excellent library very straight forward and I got it to work in no time! Here are a few tweaks I did have to make incase anyone else has problems.

ISSUE 1: TLS min requirements
add the following statement on line 167:

socket->setProtocol(QSsl::TlsV1_0OrLater);

socket->startClientEncryption();
if(!socket->waitForEncrypted(timeout))
{
qDebug() << socket->errorString();
state = Close;
}
................................................................
ISSUE 2: You may have to adjust your gmail account settings to allow insecure apps to login on your account. Also 2 factor auth must be disabled in order for it to work
................................................................
ISSUE 3:
On line 251 you call deleteLater() on the MainWindow object itself causing a segfault. This could also be related to the the function that looks a bit iffy in MainWindow::sendMail. At the very least its a memory leak.

Make Smtp a class member variable and use it as a stack allocated object rather than a heap allocated one. Then you wont have to worry about the dangling pointer.

Hi there
I am sucessfully using the Simple Smtp SSL code with QT5. It works great, the email goes through and everything seems fine, but I get the following error message:
qt.network.ssl: QSslSocket::startClientEncryption: cannot start handshake on non-plain connection

When I check, if the socket ist encrypted socket->isEncrypted() it gives a positive result.
Does this seem familiar to anyone or am I chasing ghosts unnecessarily?
Is it because we open the socket already encrypted and then the command socket->startClientEncryption() is superfluous?

Thank you all in advance!

        socket->startClientEncryption();       

        if(!socket->waitForEncrypted(timeout))
        {
            qDebug() << socket->errorString();
            state = Close;
        }
        //Send EHLO once again but now encrypted
        *t << "EHLO localhost" << "\r\n";
        t->flush();

        state = Auth;
        qDebug() << "is encrypted 2? :: " << socket->isEncrypted();
    }

There is no delete on smtp anywhere. If it has to be heap allocated it should be a smart pointer anyway.
