How do I remove an email address?
If you are using the default email configuration (aka “qmailadmin”), login to your control panel, select the “email” header at the top, followed by the “Configure your email accounts” link.
On the page that comes up, login as :
password: your postmaster password
domain: the domain for the address you want to delete (no “www” in front)
After you login, choose the type of address (POP3, forward, etc.) under the
“Edit existing address”
Next use the “Delete” link to remove the account.
