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.
We at ORCON have the submission port available to be used. We have people who have "outside ORCON" internet access who use SMTP AUTH and TLS on port 25 (Telecom Mobile/Vodafone Mobile/Xtra Hotspots etc). All Xtra connected customers will have to do is change it from SMTP port (25) to the Submission Port (587) and it will work when XTRA Block Port 25 to external mail servers to their network. Yes there is the the 465 Port (SSL before the Start of SMTP talking - as noted by other people) but I don't know many common clients which support this at all.
