Stuck: SMTP AUTH error (500 unrecognized command )

Hello,

Ciao Renzo for all the hard work!

I am SO wanting my Arduino controller boards I make for clients / projects to email daily log files. Its been a long long road. Seems to simple yet so complex.

I am now using Due clone (ARM Cortex-M3 CPU) and SPI W5500 wired Ethernet, SD etc That all works okay, and I can run the https test okay.

But I need to use my own smtp server with TLS port 587. Serer has been tested independently.

The config is:

EMailSender emailSend(“eman@wisenet.co.za”,”passsswqord”,”eman@wisenet.co.za”,”smtp.wisenet.co.za”,587);

Running my test, which is much the same as the STM32w5500_GMail_SSL_Attach_SD example, I get this on the serial monitor:

Initializing SD card…initialization done.
Begin Ethernet
DHCP OK
Ethernet Successfully Initialized
Local IP : 192.168.0.109
Subnet Mask : 255.255.255.0
Gateway IP : 192.168.0.1
DNS Server : 192.168.0.1
Write file content!
All structure created!
Sending status:
0
235
SMTP AUTH error (500 unrecognized command)

So its talking to the SMTP Server but can’t authenticate…?

I generated trust_anchor.h for wisenet.co.za,smtp.wisenet.co.za and that is in the sketch folder

I uncommented
#define SSLCLIENT_WRAPPER

As I say h/w is all tested okay with all works with the https: test example

One thing, I can’t use #include <EthernetLarge.h> it generates reams of errors like
libraries\EthernetLarge-master\Dhcp.cpp.o:C:\Users\User\Documents\Arduino\libraries\EthernetLarge-master\src/Dhcp.cpp:29: first defined here

libraries\Ethernet\Dhcp.cpp.o: In function `__static_initialization_and_destruction_0′:

So I am using #include <Ethernet.h>

Any advise highly appreciated, I really would like to get this working

Thanks.

Bruce
