When a user enters an email address associated with a remote message server account in a configuration area on a display, one or more suggestions for other field inputs are made based on canonical data or historical data from a variety of users. If the user cannot find a desired entry in the suggestions, the user may enter new information. The newly entered information (once validated) improves the prediction capability for subsequent users. A database stores information associated with each email address domain name including one or more remote message server names, one or more username patterns and ranking values. When more than one suggestion for a field is presented to a user, the suggestions are ranked in accordance with the respective ranking values such as by the popularity of a particular configuration.
