So, I have to use the mail address when using Uebimiau and the username when connecting with a local mail client? Good to know! Nevertheless thatīs not the problem here. I tried every combination of name, username, mail address and even some bad words

. The system keeps telling me the same message.
Iīm now going through all the config files again, but (donīt get me wrong) is it possible that I have to change something of the perfect setup when NOT using courier ? As I said above: Just installing courier causes
everything to work as expected! I changed nothing more than the maildir option...
By the way thanks for your help

- thatīs
real support!
