I’m new to Dreamhost. When I go to change my webmail addr from webmail.domain to mail.domain it says mail.domain is in use. I can’t find where it is being used. Any ideas? I checked settings under the mail tab and under the domain tab…

(The error I get is: “Invalid: mail..org is already being used elsewhere!”)

You cannot use mail.domain.com because that’s your POP/IMAP/SMTP server. Webmail isn’t hosted on that machine. Yes, I know it’s a bummer, but that’s a reserved subdomain name.
