Note that Telsra mobile work on a private network range which does not allow inbound port access.
You can contact Telstra and request to get a public IP added on your mobile on 125111. They will add codes onto your mobile account then you have to call 1800467889, speak to the extranet service section, choose mobile and ask them to assign the public IP.
If there is inbound port blocking on 25 and you want to run a mail server off the mobile you can use a no-ip or similar dynamic IP service to provide a fixed DNS name and external email service like spamhero.kingcomputer.com.au which will allow collection of email then forwarding of that mail to an alternate port.
