I've been scratching my head for the past 2 days trying to troubleshoot why email sending is not working on my manually installed ReportServer 3.7.1-6048 Community Edition.
the following error has been generated even though I have followed the other guides/solution related to email sending:
1) null returned by binding at net.datenwerke.rs.core.service.mail.MailModule.provideDefaultFrom()
but the 3rd parameter of net.datenwerke.rs.core.service.mail.SimpleCryptoMail.<init>(SimpleCryptoMail.java:70) is not @Nullable
at net.datenwerke.rs.core.service.mail.MailModule.provideDefaultFrom(MailModule.java:186)
at net.datenwerke.rs.core.service.mail.MailModule.provideDefaultFrom(MailModule.java:186)
while locating java.lang.String annotated with @net.datenwerke.rs.core.service.mail.annotations.MailModuleDefaultFrom()

while locating net.datenwerke.rs.core.service.mail.SimpleCryptoMail annotated with @com.google.inject.internal.UniqueAnnotatio
ns$Internal(value=1)

I have done the following configurations:
1) in /FileServer/etc/mail/mail.cf:
<?xml version="1.0" encoding="UTF-8"?>
<!--

<mail>

</configuration>
the password only has alphanumeric and underscore
2) in /FileServer/etc/datasinks/datasinks.cf:
<?xml version="1.0" encoding="UTF-8"?>
<!--

I've restarted the tomcat server every time changing the configuration as well as clicking on the apply button... but unfortunately nothing works and it is very frustrating...
I've check the source code of SimpleCryptoMail.java for that 3rd parameters and it was pointing to the 'from' parameter... based on the config... the from parameter should already been defined based on the 'Sender' key from the config xml... So.. at the moment I really don't have any clue how to proceed further to resolve the issue.
The following is my server setup:
OS: Ubuntu 20.04
Java: openjdk 11.0.11 (default ubuntu repo)
Tomcat: Tomcat 9 (default ubuntu repo)
Reverse Proxy: Nginx (default ubuntu repo) serving HTTPS in front of the tomcat
Database: Mysql 8.0.26 (default ubuntu repo)
Thanks in advance for any pointers to help me resolve this issue.

I have made further test but unfortunately still got the same error.
I've installed simple SMTP server for development (MailSlurper) and don't use any authentication at all... make configuration to the email Datasink and fileserver/etc/mail/mail.cf to reflect the changes (no user id and password required.. no ssl, no tls... plain smtp).
the same error popup when I test the email datasink.

I've managed to make the email work now. I still do not know what is the root cause of the problem but what I did is by just referring to the config posted by Mirza in the following topic: https://forum.reportserver.net/viewtopic.php?id=616
I just copied the config... overwrite my mail.cf and restart the tomcat... then suddenly everything went OK... before that I have followed the same configuration but I do not copy and paste it... I just write directly to the existing default in that file and make the necessary editing.
Maybe something is off with the default config file and by just editing and changing the value won't help... overwriting the whole file with what Mirza's config as in that post and after that changing the value to one's environment seems to resolve the issue.

Hi Salleh,
sorry for the late answer.
I checked the differences between your file and the template file, and the only difference is:
<!--
ReportServer Configuration File
filename: mail/mail.cf
-------------
Deprecated: Use email SMTP datasinks instead with default email datasink.
-------------
Configures email server settings.
-->if I put this in my mail.cf, I get your same error message. Something seems to be wrong with the comment, I think the "-------". We will correct this.
Anyway, if you copy the settings into an email datasink, it should also work, can you pls try this? You can use the "test datasink" button for testing.

Eduardo

Hi Salleh,
we changed the default mail.cf comment to:
<!--
ReportServer Configuration File
filename: mail/mail.cf
==========
Deprecated: Use email SMTP datasinks instead with default email datasink.
==========
Configures email server settings.
-->and now it works. We will fix this in the next ReportServer's version.
