port 587 with ssl ANS TLS not working

Hi Pim,
Wich platform do you use??

I am having the same problem.

I have an “Arduino Uno Wifi Rev2” board.

I am trying to use Gmail but I have also tried Yahoo and Office365.

I have confirmed SMTP works on my laptop by creating a quick program in Visual Studio 2019 (Windows 10). In that test program, I am unable to send emails on port 465 but emails do work on port 587. This is the case with gmail, yahoo and Office365.

I have used the same settings on Arduino but consistently get a “timeout” when trying to send an email. WiFi connects fine.

I did have to change the includes to this for your basic send example:

#include <EMailSender.h>
#include <WiFiNINA.h>
#include <UIPEthernet.h>

My constructor is:

EMailSender emailSend(“[my email]@gmail.com”, “[my password]”, “[my email]@gmail.com”, “[my name]”, “smtp.gmail.com”, 587);

Thanks!

Hi mjorrens,
Yes, that device is fantastic, I’ve used also esp8266 and esp32, but MKR WiFi 1010 is very powerful.

You can refer this article
Send email with attachments: Arduino SAMD boards (WiFiNINA) – 3

But Arduini UNO work with sendgrid if you need.

Great! Perhaps remove reference to the Arduino UNO WiFi Rev.2 in that article or add a note that it will not work with gmail.

I will let you know how it goes with the MKR Wifi 1010.
