Send email using SMTP STARTTLS.

Send email using SMTP STARTTLS. With STARTTLS, the SMTP client connects to the SMTP server on port 25 (non-SSL) and then issues a STARTTLS command to convert the connection to a secure TLS channel. Swift

func chilkatTest() {
    var success: Bool = false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // The mailman object is used for sending and receiving email.
    let mailman = CkoMailMan()!

    // Set the SMTP server.
    mailman.smtpHost = "smtp.mymailserver.com"

    mailman.smtpUsername = "myLogin"
    mailman.smtpPassword = "myPassword"

    mailman.startTLS = true

    // Create a new email object
    let email = CkoEmail()!

    email.subject = "This is a test"
    email.body = "This is a test"
    email.from = "Chilkat Support <support@chilkatsoft.com>"
    success = email.add(to: "Chilkat Admin", emailAddress: "admin@chilkatsoft.com")

    success = mailman.sendEmail(email: email)
    if success != true {
        print("\(mailman.lastErrorText!)")
        return
    }

    success = mailman.closeSmtpConnection()
    if success != true {
        print("Connection to SMTP server not closed cleanly.")
    }

    print("Mail Sent!")
