Unable to log in/authenticate a username in web mail. If it is possible to login to one post office but not others then chances are that the username is not in the first post office entered into the system or the default. The default post office can be set in the server properties of "localhost".
Unless a user is in the default post office then a full format of the username is required to be entered for a username login, such as firstname.lastname@example.org. The reason it may work with one domain/post office, is that the first post office that is added is set as the default post office in MailEnable. The default post office does not require the "@postoffice" part of the username.
In the Enterprise Edition of MailEnable it is possible to bind post offices and effectively domains to post offices, meaning that a simple username and no post office extension is required for login for all post offices.
