It just means that there is no mailbox for [email protected], so you can not send a email to this account. If you want to receive emails for this account, create it.
Hm, I don't want recieve emails for it. I mean that email without an emailaccount should not be able to get in any queue and I don't understand why it does.
That's funny ... Ok, very seriously now. This user does not exist and postfix shuld not accept a mail for a user which not exist. Is'nt it the goal?
Have a look in your aliases file, maybe you have an alias for webmaster in there. The aliases file is not managed by ISPConfig.
Of cource /etc/aliaces is there but no postfix alias-table-file. I suppose eben this problem has been solved be the change from sendmail to postfix style. Have a great time, and thanks a lot for your help and ISPConfig!!!
