Nextlcoud 17.0.5 Centos 7.5
I’m getting this error suddenly. What I can’t find is where the logs are at when you send a test email and get an error.
A problem occurred while sending the email. Please revise your settings. (Error: Expected response code 220 but got code "554", with message "554-perfora.net (mreueus004) Nemesis ESMTP Service not available 554-No SMTP service 554 IP address is black listed. ")
The IP of the server isn’t on any black lists but neither is the provider which is ionos.
Where can i find a log where this information might be?
