which step is the slowest? why don't u make it ASync?

It is up to anyone according to usage mode, for me following worked well ` void SmtpNotifier::notify(QString message) { // do not block main thread sending the mail auto result = QtConcurrent::run(sendMail, this, m_smtpServer, m_smtpPort, m_recipients, message); Q_UNUSED(result); }

void SmtpNotifier::sendMail(SmtpNotifier *notifier, QString server, uint port, QStringList recipients, QString message) { SmtpClient smtp(server, port, SmtpClient::TcpConnection);

connect(&smtp, &SmtpClient::smtpError, notifier, &SmtpNotifier::handleSmtpError);

const auto theSender = QString{"sender@mydomain.com"};

smtp.setUser(theSender);
smtp.setConnectionTimeout(std::chrono::seconds(30));
smtp.setResponseTimeout(std::chrono::seconds(30));
smtp.setAuthMethod(SmtpClient::AuthLogin);
// smtp.setPassword(); // no password when inside of companmy network

MimeMessage mimeMsg;
mimeMsg.setSender(EmailAddress(theSender, tr("my application")));
for (const auto &recipientAddress : recipients)
{
    mimeMsg.addRecipient(EmailAddress(recipientAddress));
}
mimeMsg.setSubject("Value threshold exceeded");

MimeText text;
text.setText(message + "\r\n\r\n" + tr("Your application"));

mimeMsg.addPart(&text);

smtp.connectToHost();
smtp.login();
smtp.sendMail(mimeMsg);
smtp.quit();

} `

Slowest part is usually(!) the sendMail() bit, as most of the data transfer happens here.

An Asynchronous mode is added in v2.0 of the library.
