When you are creating new account the default email will be same username of new account, How I can change the default email to be webmaster@newaccount.com when create any new account?

Thank you.

That must be done in the control panel for the accuont itself. Go into the cPanel for the account -> Mail Manager -> Default Address -> Set default address.

Thank you.

Sorry I don't need this, I need to change all new accounts on my server by root.

Any one help me please.:confused:

I am not sure if I understand this question. I am not so sure you understand the question.

What you are talking about depends on the CP you are using. Just about all that I have seen creates admin@domainname.com. I think you are asking about Catch-alls. I am not sure how you would configure it up via your control panel, it really depends. You can change this manually via your sendmail settings (ie /etc/virtusertable or /etc/mail/virtusertable and the aliases file therein). But that can get hairy if you do not feel comfortable enough with sendmail.

Let me see if I understand: you want every new account to have their default mailbox be webmaster@theirdomain.com instead of their username, and you want it done automatically when the account is set up? If that is the case, why? Most users like to select the default address they want to use. I know I would...

Yes, I want this.
