Hi,

Return-Path: <>  is set by MAIL FROM: parameter, but is set by the SMTP server.

It’s strange that is empty.

[Renzo Mischianti]

Yes the library convert in base 64, but the code you posted use smtp from orange not sendgrid.

I don’t have w5500, i’m going to order one of that to do some test.

Theorically it can support secure connection, but i think some test is needed.

Hi Helano,

in the repo you don’t use EmailSender library, try to use the library you can avoid a lot of problem.

Bye Renzo

[Renzo Mischianti]

Hi Gilles,

you can’t use GMail or Orange with Arduino Ethernet because It not support secure connection.

SendGrid is not so simple to configure in this long topic we cover all configuration step of the service.

Ahh wait.. I use an esp8266, Arduino Mega can’t work with this service, because It need SSL/TSL encoding.

 

You must use a service like sendgrid

Or you must change device, you can get an Arduino SAMD like here

check here, I explain witch service you can use.

Hi Gilles,
I check and try, I think the problem is the from IP.

If I try to send with GMail verso Orange It work correctly, but if i try from Orange to Orange It go to SPAM

with error 125 (that it is greater than 100) at this link say that error > 100

There is an additional header called “X-ME-spam cause”. If the value in this first bracket is higher than 100, then Vade Secure has flagged your mail as spam.

And in the detail of message

Received : from opme11dod06nd1.rouen.francetelecom.fr ([10.79.5.102]) by opme11dob14nd1.rouen.francetelecom.fr with LMTP id MNDOK8P9PGDoWwAASTXmBw ; Mon, 01 Mar 2021 15:44:19 +0100,from opme11ppr01nd1.rouen.francetelecom.fr ([10.79.5.102]) by opme11dod06nd1.rouen.francetelecom.fr with LMTP id iIG2K8P9PGD+RQAAhj82FQ ; Mon, 01 Mar 2021 15:44:19 +0100,from mwinf5d03 ([10.79.5.102]) by opme11ppr01nd1.rouen.francetelecom.fr with LMTP id eOj5DsP9PGAYHAAAKPHnNg (envelope-from <renzo.mischianti@orange.fr>) for <renzo.mischianti@orange.fr>; Mon, 01 Mar 2021 15:44:19 +0100,from mischianti: ([212.216.211.182]) by mwinf5d03 with ME id b2kC2400L3wge1w032kDW4; Mon, 01 Mar 2021 15:44:19 +0100

And you can check https://www.spamhaus.org/query/ip/212.216.211.182 that the FROM IP is market as spam.

So the result is that orange.fr with his service Vade Secure block orange.fr SMTP emails. You can try to write to your company to fix this wrong categorization.

Hi helaino,
sorry but I don’t understand, can you explain better with a code example.
Thanks Renzo

[Renzo Mischianti]

Hi Gilles,
It’s an unexpected behavior the use of an array of 0 lenght, I must look the code to check what happens in that situation.
Bye Renzo

[Renzo Mischianti]

Hi Gilles,
if you can do a mail for me I try this or tomorrow evening to do the change.
Send me the password to info@mischianti.org .
Bye Renzo

[Renzo Mischianti]

Hi Gilles,
only for confirmation, you use an Arduino Mega and a w5100 shield, and can you tell me the size of the file you want send?
Bye Renzo

[Renzo Mischianti]

Hi max7777,
I try the code with my WeMos D1 mini, and It’s work correctly.
You had follow the tutorial to enable less secure app or application passwd?

Send email with attachments (EMailSender v2.x library): esp32 and esp8266 – 2

Bye Renzo

[Renzo Mischianti]

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.

Bye Renzo

[Renzo Mischianti]

Hi majorrens,
GMail and other services that need TSL can’t work with Arduino UNO or Mega, you must use not encrypted service like sendgrid, refer to the article

Hi Ludopot,
finally i receive the response about compatibility.

Hi Renzo,

Sorry for the late reply because we just get back to work.

For your questions:
I need information, do the transmitters “E90-DTU (400SL22P)” and “E22-400T22D” communicate with each other? Can I use these devices to send and receive data?
Answer is Yes. E90-DTU (400SL22P) can tranceive data with E22-400T22D.

Is There a table of compatibility devices?

For your reference:
1.E90-DTU+ L+xxx use E32 modules inside. so E90-DTU+L can work E32-T modules if their frequency is same(433/915).
2.E90-DTU+ SL+xxx use E22 modules inside. so E90-DTU+SL can work E22-T modules if their frequency is same(433/915).

Best Regards,
