Problems with eMail

[Konrad Schwarz]

Hi All,
thanks for developing OpenMeeting.
1st steps i did with the 5.0.0.1-M3-docker Version - Then i decidet to
do a full installation.

With some smal isues the tutorials work fine:

Installation OpenMeetings 5.0.0-M3 on Ubuntu 18.04 LTS.pdf
I did not install MariaDB, mySQL 5.7.29 was installed on the Server.

Additionaly: 
Installation SSL certificates and Coturn for OpenMeetings 5.0.0-M3.pdf

Than i decided direct to use the RSA-Certificates from Letyencrypt (See
the config.xml).
It was a bit work:
the apt of ubuntu 18.03 LTS installs APR based Apache Tomcat Native
library version 1.2.21
but tomcat needs 1.2.23
So i downloaded and compiled Apache Tomcat Native library V1.2.23

Now nearly everything works -

But sending email does not work.
If a new user does the registration, the email does not work.

i configured the Parameters  like in every other Software, using TLS
eMail-Adress and pass are ok.


I found the attached error in the catalina-out - Log

Has anyone an idea to solve that ?

Regards

Koni
