Hi again.. I keep trying... maybe I will get an answer this time. I have set up a system according to this tutorial. It works ok. I can log on, I installed roundcube but I cant send mails. in the DB I have my.domain.tld : when trying to send an email to myself so from [email protected] to [email protected] I get this error message in the log: I made the interesting part bold... How is that I dont have that user? I have him in the mysql database. Whats up with this?
