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

Hey Renzo,

i got the same problem if i connect my wemos d1 mini to the company network. At home it works fine. Do i have to open some ports to ensure the connection to the smtp server? If yes, which ports do i need to open?

Thanks in advance

Kind Regards,

Deniz Braun

Hey Renzo, thank you for your fast reply!

I think, i have to talk with the network admin tomorrow, so he can open the port for me.

I’ll report the result tomorrow. I guess a lot of people have this problem, so it would ne nice, if it works then.

Kind regards,

Deniz Braun
