Re: 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@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@2c2axxx.online-server.cloud which
doesn't exist.
