Hello!

I faced a problem that I can send email through "gmail function" successfully, but gmail will not send the notification when gmail receive the email that I sent, it just shows up in the gmail.

Does anyone face the same situation? Thanks in advance.

Sorry, I don't understand the text. Please try to rephrase.

OKay~ I mean that when I use "gmail" smtp server to send email. the email will be sent successfully but without the notification from gmail app. And when I use the same "gmail" smtp server to send email in Python, the email will be sent successfully and with the notification from gmail app.

I don't know does anyone face the same situation, or just there is something that I didn't notice.

Please verify that the accounts are different. The account used for the SMTP server must not be the same account, which receives the mail. Google won't display any notifications if they are the same.

If they are different, send me 2 emails: one from dart mailer, and one from your python program. (git@3.141.email)

I have the same issue and this is my function The email is sent successfully but the user never receives it if the service is from @gmail.com.

PS: this only happens if I use mailer, if I send an email from the panel offered by ionos to an email @gmail.com, the email is sent and the recipient receives it correctly.

Future<void> sendNotificationEmail(String userId) async {
  final email = 'support@themonstersapp.com';
  final password = '******';
  final server = 'smtp.ionos.com';

  final smtpServer = SmtpServer(
    server,
    username: email,
    password: password,
  );

  final message = Message()
    ..from = Address('no-reply@dmtraining.themonstersapp.com', 'DMTraining')
    ..recipients.add(auth.currentUser!.email)
    ..subject = '${S.current.securityalertfor} ${auth.currentUser!.email}'
    ..text =
        'Text';

  bool isConnected = false;
  while (!isConnected) {
    try {
      final connection = PersistentConnection(smtpServer);
      await connection.send(message);
      await connection.close();
      isConnected = true;
    } on MailerException catch (e) {
      String? error = '';

      switch (e.toString()) {
        case 'Authentication Failed (code: 535), response:\n< Authentication credentials invalid':
          error = 'Error (code: 535) try again later ';
          break;

        default:
          error;
          break;
      }

    }
  }
}

@xTheMasters I am not 100% sure I what you mean with "if the service is from @gmail.com". Do you mean, that you can't send mails to any @gmail.com address?

If this is the case, please "forward" me 2 mails, one sent using the mailer library, one sent using ionos, so that I can compare them. Please make sure, that you send me "originals" (including headers,...). (christian@loitsch.com)

@xTheMasters I've responded to your mails.

The problem I found was missing SPF DNS entries, which probably increased the chance of mails being blocked.

@TONYCHOU81905 Did we fix your issues?

I am pretty confident, that the problems mentioned here are not bugs in the mailer library.

If you (or other users of this library) still have problems either reopen this issue, or contact me directly (christian@loitsch.com)

Hi~@close2

Actually, I have no idea why this problem happens. But I thought maybe it's because of the encoding I changed the name of the Address from Chinese to English, and then I can receive notifications from gmail.

Thank you for working with me to solve the problem：）
