B4J Question [SOLVED] Email Server

hi!
With which email you are using it? because gmail will cause you a lot of problems. Beyond that, have you tried with your firewall of? if you are doing it within your company they may have a special protection for pop and smtp ports.

Hi .
I tried with gmail.com, gmx.de and web.de.
All certificates are saved in cacerts file.
gmx.de allows to change the port from 587 (StartTLS) to 465 (SSL) but this also don´t work.

Start with Gmail.

It should be:

You do need to enable access for "less secure applications": https://support.google.com/accounts/answer/6010255?hl=en

Thx Erel, but don´t work

Do you get the certificate error?

Yes Erel, always certificate error.
But a few minutes ago, i found the solution.

All tutorials for the certificate error, describe the solution with the JAVA_PATH

A normal user installs java and has eg C:\Program Files\Java\jre1.8.0_121 as JAVA_PATH.
So after using the InstallCert.jar you have to put the new jssecacerts inside your JAVA_PATH\lib\security (there is the cacerts located, too)

But ......

If you´ve the jdk installed, your JAVA_PATH is as described above AND you have inside the jdk directory an .....\jre\lib\security folder.
Inside this, you find a cacerts file too, and you have to put the jssecacerts file inside this folder while debug the app.

This was my mistake.

Thanks to all who helped.
