User doesn't exist

I try to use dovecot as a MTA with postfix.
But it does not accept incoming mails.
Why does it not work?

[root at localhost bruno]# dovecot --version

Hi,

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

User doesn't exist

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
