function Get-DbaDbMail {
    <#
        .SYNOPSIS
            Gets the database mail from SQL Server
 
        .DESCRIPTION
            Gets the database mail from SQL Server
 
        .PARAMETER SqlInstance
            The SQL Server instance, or instances.
 
        .PARAMETER SqlCredential
            Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
