Oh, yeah. how to fix. Well, It's SMTP. There's a SysConfig option (Sendmail?) for that. Likely you've put a username and password for your SMTP server that isn't correct/has changed/doesn't like your otrs ip address. I know you wanted help, but at least a bit of searchinghttps://www.google.com/search?q=site:forums.otterhub.org+smtp+authentication...might be useful, then come back with what you've tried and what doesn't work.
