Error
See this Stackoverflow answer: You have enabled Two phase authentication for your Google account and as a result applications will not be able to login to your Google account using the actual password. Google expects you to generate a application specific password for each application you use (and give it a name) and then use that password to login to your Google account from your application. This allows you to not give your password to third party application when you have 2-step authentication enabled. See here what to do.

Perfect. Thanks!
Hello,
this is a great extension, but I don't get an email. What am I doing wrong?
Thank you for your help!
Greetings Heiko 
You are using gmail. See the posts above yours!
Sorry, but I'm stuck, where can the mistake be? Here are three more blocks.
for Gmail you need to set up App passwords as explained earlier SmtpClient: An extension to send emails using SMTP server - #210 by Taifun
for GMX I would try SSL together with port 465
Taifun
Oh, now I get it too. 
Thank you for your help!!

Shouldn't host be smtp.gmail.com instead of stmp.gmail.com ?

Generate App Specific Password.
You seem to be using two accounts on community.
Which one should I delete?
Only one account is allowed here.

You should put your app name there.
Then you will get a password for your email which you can use in SmtpClient extension.
Yes but hes doesn't work
Show blocks.

HI,
here is a strange thing.
This extension (com.sunny.SmtpClient.aix) works well
And this (Beta version of a client with support for smtp, pop3 and imap - Extensions - Kodular Community) works well also.
But If I import theese two extensions in the same AppInventor Project, when I build APK I receive the following error :
App Inventor is unable to compile this project.
The compiler error output was
