Log4j2 SMTP-Appender "Must issue a STARTTLS command first"

I am trying to send log entries with severity "error" via email in java. In my log4j2.xml file I have the following SMTP appender:

<SMTP>
name="Mail"
subject="Error Log"
to="[email protected]"
from="[email protected]"
smtpHost="SMTP-Host"
smtpPort="587"
smtpPassword="[password]" 
smtpUsername="[email protected]"
smtpDebug="true"
ignoreExceptions="false"
bufferSize="4"
smtpProtocol="smtp">
</SMTP>

But when I run my programm (which consists of a main logging a string) the following error occurs:

DEBUG: setDebug: JavaMail version 1.4.7
13:13:44.469 [main] ERROR Main - Test Error

As far as I understand the programm can establish a connection to the server but then Must issue a STARTTLS command first this happens. Can someone explain to me what that means and how to fix it?

When I searched for the error I got a few posts with similar problems but not with log4j2 but with java.mail and they didn't helped me.

I tried using smtpPort="465" and smtpProtocol="smtps" but in both cases the connection got refused.

I have no more new ideas and am grateful for everyone who helps me.

I had the same issue and it looks like log4j2 is not capable of handling STARTTLS. Fortunately log4j uses the system properties when creating the mail session. So my fix is using

smtpProtocol="smtp"

for the SMTP appender and setting the system property

mail.smtp.starttls.enable=true

on the command line to activate STARTTLS for the mail session. You could alternatively use

System.setProperty("mail.smtp.starttls.enable", "true")

in your application code.
