User doesn't exist

[Bruno Kiste]

Hello,

well, the user "bruno" does exist.
Can I make it ignore the hostname part or accept the user "bruno" as
"bruno at 2c2axxx.online-server.cloud"?
Can I change the lookup in dovecot or do I have to edit the postfix
configuration?

Best wishes,

Bruno

    Hi,

    it seems to look for user bruno at 2c2axxx.online-server.cloud which
    doesn't exist.
