I have an SMTP Server without SSL / TLS but if I want to send an mail I always get this error.
Im using an MEGA with ENC28J60 Shield.
I used 0 / 0 as login because the Server doesnt need them.
Here is my Code:
// Includes
#include <Arduino.h>
#include <EMailSender.h>
#include <IPAddress.h>
// Set Mail Params
EMailSender emailSend("0","0","test@test.com","SmartTest","IP of SMTP",25); // to be defined
//
byte mac[] = { 0xAA, 0xCD, 0xBE, 0xEF, 0xDD };
// the setup function runs once when you press reset or power the board
void setup()
{
// INIT
Serial.begin(115200);
Ethernet.init(53);
Ethernet.begin(mac);
Serial.println("IP: ");
Serial.println(Ethernet.localIP());
EMailSender::EMailMessage message;
message.subject = "Test";
message.message = "Bestanden!";
EMailSender::Response resp = emailSend.send("smarttest@gmail.com", message);
Serial.println(resp.status);
Serial.println(resp.code);
Serial.println(resp.desc);
}
// the loop function runs over and over again until power down or reset
void loop() {
}
To fix this you need to add the full domain name or a workgroup name to the network identification.
Open the System Properties and go to the Computer Name tab (Network Identification on Win2000 server). You will see “MACHINE-name.” in the full computer name field. You will need to append your full domain name or workgroup name here. Click the “Change” button (Properties for Win2k) on the Computer Name tab, then click “More”. Enter the full domain name or workgroup name in the “Primary DNS suffix of this computer” and click OK. After you OK the change, you will be required to reboot.
When you come back up, the Network ID page should show the Full machine.domain.com name.
Other causes may be, a failure to assign a valid email address to the mandatory From property:
Mail.From = “name@domain.com”
This error may also occur if a name instead of an email address is specified for this property. Another reason is, invalid syntax in an email address passed to any of the methods: AddAddress, AddCC, AddBcc or AddReplyTo.
I think the second part can help you.
I don’t need if necessary for your provider (but I think no) you can set the value to HELO message with emailSend.setPublicIpDescriptor(<Value of HELO>)
If you don’t need authentication you must set It with this command
Hi Renzo, I tried your solution but Im still running in the same error.
What did you mean by that qoute, because my EMailFrom is set to the correct Form:
“mail@domain.com”
I also found out that the Mail Server would not connect me all the time, like half of the time the connection timed out. Could that be a reason I should look at?
