There seem to be many who feel there is no overwhelming reason to support 587. I can certainly see that point of view, but I guess my question is what reasons do those of you with that viewpoint have *not* to implement it? I just don't see the harm in either configuring your MTA to listen on an extra port, or just forward port 587 to 25 at the network level. Other than a few man-hours for implementation what are the added costs/risks that make you so reluctant? What am I missing? Andrew
