SMTP DATA error! SMTP Response TIMEOUT!

abort() was called at PC 0x4018b7f6 on core 1

The board crashes and restarts.

Any ideas? The file I'm trying to send is only 48 bytes.

The sending function:

int sendEmail(fs::FS &fs, const char * path){
  File dir = SPIFFS.open("/");
    File file = dir.openNextFile();
    while (file) {
        Serial.println(file.name());
        Serial.println(file.size());

        file = dir.openNextFile();
    }
  EMailSender::EMailMessage message;
    message.subject = "New Picture!";
    message.message = "Your WiFi ESP32 Cam has sent a new picture! Enjoy!";
    EMailSender::FileDescriptior fileDescriptor[1];
    fileDescriptor[0].filename = F("msg.txt");
    fileDescriptor[0].url = F("/msg.txt");
    fileDescriptor[0].mime = "text/plain";
    fileDescriptor[0].encode64 = false;
    fileDescriptor[0].storageType = EMailSender::EMAIL_STORAGE_TYPE_SPIFFS;

    EMailSender::Attachments attachs = {1, fileDescriptor};
    EMailSender::Response resp = emailSend.send(sett.receiver_email, message, attachs);
    Serial.println("Sending status: ");
    Serial.println(resp.status);
    Serial.println(resp.code);
    Serial.println(resp.desc);
}

Sorry for the late response, I try it, and It works. Check your network firewall or something similar. Bye Renzo
