> which is why I think spf won't make it. If port 587 is enabled and used as it should, there's no problem. Beyond that, port 587 guarded by AUTH also permits roaming users. Otherwise they often have to change their mail settings each time they plug into a new network. Some services, like Shaw, have internal mail servers which aren't even visible to the outside world. If we have to get 587 up and running for roaming users, then why on Earth wouldn't SPF be a natural extension of that? I mean, if you want your customers to send through your mail system to guarantee that it will work whether they're in Chicago, Paris or Tokyo, then popping an SPF record on your domain is just an added way of giving the client's messages a leg-up. -- Aaron Clausen To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
