By default, IMail Server forces users to authenticate, unless you select another option such as Relay Mail for Anyone or Relay Mail for Addresses in the Mail Relay Settings (located at the Services tab > SMTP). This means that every time a user connects to the IMail Server, he/she must enter a user ID and password.
Domain Administrators cannot delete System Administrator accounts, permissions, or change other System Administrator settings. Domain Administrators will not display System Administrator rules or file directory information.
Hyphens can be used in the user ID, but be aware that IMail Server will use the last hyphen in the user ID to delimit a mailbox name.
Example: If mail is sent to the address mr-fred-account@ipswitch.com, IMail Server reads "accounts" as a mailbox that belongs to mr-fred.
Note: You can change the character used to delimit the mailbox name in a user ID. In the Windows NT registry, add a "GLOBAL IMail key of MailBoxSplitChar" and specify the new character as the first character of the string value.
