To determine what mail is on a mail list, the @mail command has been provided.
@mail <range> on <*list-name>
This command form will return the list of mail messages on the mail list from the beginning to the end of the specified range. If the range is not specified, it defaults to a value based on the number of rows you have told Cold (via @set cols) exist on your screen.
@mail <*list-name>
This command form will return the same list of messages as the form above, but assumes the default range.
