[nznog] Port 25

Just a quick email to the list to find out what other service providers are doing regarding XTRA blocking port 25 when your company does not provide internet connections, so many of your customers are using xtra as a service provider but not for other services wuch as mail. Many of my customers are XTRA customers, but are also vodafone etc etc, so an external autheticated mail server is a huge bonus for them. Use secure port? Regards, Simon
