It seems like a bug and will confirm and fix in next release. In the meantime, you can manually change this by open rsreportserver.config (<root>\Microsoft Power BI Report Server\PBIRS\ReportServer\), find the following line and change “True” to “False”:

<SMTPUseSSL>True</SMTPUseSSL>

Then restart the server.
