@JoshData outbound mails get rejected, as domain is not pointed to box yet (see above) - this is an expected behavior. (“450 sender address rejected domain not found)”
when i do a login on webmail (45.454.544.54/mail) (roundcube login page shown correctly) it follows a blank page (45.454.544.54/mail/?_task=login) but then the user directory (completely empty) gets created for the user i tried to login through webmail.
ps used echo “test” | mail -s test email@somewhere.com and viewed mail.log
