Hi Joergen,

I think the relevant error is

501 5.5.2 <mischianti:>: Helo command rejected: Invalid name

probably you aren’t attached to the Sunrise contract line, and you can use SMTP only with Sunrise line.

For example, if you have a Sunrise cellular line and you try to access SMTP via your home line the provider reject the request.

As test (if you don’t use a mail client) you can try to configure a client like Outlook to send email from the same line.

 

Tell me if is this the problem.

Bye Renzo

Hello Renzo,

presently, I use tj.braazola@sunrise.ch as my default email Address in gmail.

As a Matter of Fact, emailsender works fine with a gmail Address.

For the Time being, I’ll give up with Sunrise SMTP.

It’s more urgent for me to have LittleFS working.

 

Cheers

Hi Joergen,
sorry to write so late, I add support for LittleFS in this versione of EMailSender
Send email with attachments (EMailSender v2.x library): esp32 and esp8266 – 2

And also update a library of FTP Server to support LittleFS.
FTP server on esp8266 and esp32

Bye Renzo

Great, I’ll give it a try ASAP!

Thanks  a lot. Cheers
