> redirecting all outbound port 25 traffic to our smtp server Doesn't that create a lot of extra work for you, or problems for your clients? For example, when they use their office server mail from home, or an Internet born Email service such as from their Web site provider (usually with smtp auth), and your SMTP server not listed as an approved sending server in their SPF records? You usually dont want to be be a SPF approved sender for a domain owned by a high valoume web provder.
