I believe that smtp.xtra.co.nz will accept any incoming email from an email
client as long as it has originated from an IP address that Xtra "Owns"

Obviously it also accepts any email from mail servers no matter the ip
address (unless "blacklisted")

IE You are connected via Xtra dial up, Xtra Jetstream or have been allocated
a fixed ip from Xtra.

Same technique is used to limit access to pop3.xtra.co.nz to collect email.

If you connect via an Xtra ip address then you have access. Connect not
using an Xtra ip address and NO EMAIL. That is why when using the ipass
product from Xtra when travelling you need to change your pop3 address in
the email client.

They do not look at the "from domain name in the emails!!
