I have problems with email account from one domain

[rutame]

Hello.

When installed Ispconfig en Ubuntu Server 8.04 i gave a host name and domain name, well, this domain is domain.com then i create and site with the same domain name and as host "www" when i create and email account for this domain dont recive emails and does not let me enter in webmail, is as this account does not exist.

Could that be for the domain name? if is so how i could change the ispconfig server name (and all domain names refer to server) for fix this?

I hope explain me more or less but my english no is good.

Thank you very much

Which error message do you get in the mail log?

[rutame]

Hello Till, how are you?

The error that the other server returned was: 550 550 5.1.1 <user@grafycomp.com>: Recipient address rejected: User unknown in local recipient table (state 14).

I think that error is because my server has domain grafycomp.com the same that other site. For this i would like change the server name (domain).

Thank you

Is the amil address user@grafycomp.com listed in /etc/postfix/virtusertable? If not, there might be a co-domain grafycomp.com with empty hostname missing in the website www.grafycomp.com
