    Hi there,

    Got a little issue i do not get resolved. Hope you can help..
    Setting up ISPConfig was easy, but ran into the following.

    I had a domain setup with several users / aliasses and mailinglists. all worked fine..
    then deleted a mailinglist and instead created a normal account . But this account does not want to recieve mails.
    I can log in to roundcube with this user. I can see the vmail dir for the user gets created..
    All other accounts work fine, if i create a new account with different name it works fine..
    just this one which has been a mailinglist does not want to recieve mails it seems

    Hope anyone can give me some direction where to look..

    error i can see is:
    Action: failed
    Status: 5.1.1
    Diagnostic-Code: X-Postfix; unknown user: "<username>"
