Hello,
regarding the mail notifications I have a problem: I cannot send any mail. After trying and trying I really need some help.
I have a smtp server at a german hoster (xxxxx.alfahosting-server.de) and want to connect via TLS 587 as it has been working over years in Outlook.
But my syslog shows errors:
Code

Thank you very much in advance for your help!
