Hello,
unfortunatelly, there is no error. The the last entry in SMTP log (of Exchange server) is successfull authentication and that´s all.
Besides, the install script http://localhost/otrs/installer.pl found IMAPS and SMTPS is working fine….

That error is coming from the remote SMTP server. There should be a message logged on their side as to what address you are actually sending in the SMTP envelope and the address it’s coming from. Contact your SMTP provider and ask them for that data and what IP ranges from which you are authorized to send. Are you using SPF records in your DNS? If so, then default config of modern versions of sendmail enforces SPF declared mail servers. I doubt that your new OTRS server is declared as a legitimate source of email if you’re in early testing.
