swift - 使用 mailCore2 发送电子邮件给出错误代码 = 30

Question

我正在使用 MailCore2 框架发送电子邮件。我没有使用 MFMailComposer 因为要求就是没有任何电子邮件用户界面。我们只是获取电子邮件 ID，然后单击按钮发送一些信息到电子邮件地址。这是我下面提到的代码

 func sendEmailToCustomer(emailid:String?)
    {
        let session : MCOSMTPSession = MCOSMTPSession()
        session.hostname = "mail.***.com"
        session.port = 25
        session.connectionType = MCOConnectionType.clear

        let builder = MCOMessageBuilder()
        builder.header.from = MCOAddress(displayName: " iPad App", mailbox:"INVESTOR@xxx.com")
        builder.header.to = [MCOAddress(displayName: "iPad App", mailbox:emailid)]

        builder.header.subject = "Email Link   \(NSUserDefaults.standardUserDefaults().valueForKey("branch_id")!)"
        builder.htmlBody = "Thanks for choosing . Here is link you wanted to have in your inbox \n  \((webView.request?.URL?.absoluteString)!))"
        let data = builder.data()

        let sendOperation : MCOSMTPSendOperation = session.sendOperationWithData(data)
        NSUserDefaults .standardUserDefaults().setValue(emailid, forKey: "Customer_EmailId")
        sendOperation.start({
            (error : NSError?) -> Void in

            if(error != nil){
                //Keep sending the email till it succeeds.  needs to know for security reasons.
               // self.sendEmailToCustomer(emailid)
                print("customer email failed.\(error?.code) \(error)")
                self.showAlertMessage(MESSAGE_EMAIL_Not_SENT, title:"Email Not Sent", actions: [UIAlertAction(title: "OK", style: .Default) {action in
                    }], withSound: false)
                Crittercism.leaveBreadcrumb("customer email failed")
            }
            else{
                //Email sent successfully.

                print("Email sent successfully \(emailid)")
                self.showAlertMessage(MESSAGE_EMAIL_SENT, title:"Email Sent", actions: [UIAlertAction(title: "OK", style: .Default) {action in
                    }], withSound: false)

            }
        })
    }

当我的“收件人”电子邮件在组织中时，它工作正常。但如果我尝试向外部人员发送电子邮件帐户，然后收到错误“Error Domain=MCOErrorDomain Code=30”我尝试更改不同的端口、连接类型。什么都不起作用。请帮忙

您的问题与mailcore2无关，而是与您正在使用的邮件服务器有关。您收到的错误消息“550 Denied forexternal Relay”意味着您正在连接的邮件服务器未配置为允许您发送到其他域。如果您认为该配置有错误，请与该 smtp 服务器的邮局管理员联系。 (postmaster@，插入服务器的域名而不是 )
