I'm having problems sending emails from my own domain and I'm on Xtra
A few years ago, Xtra changed their system so that all email traffic using "port 25" get blocked. Needless to say, it's caused a number of problems for many of our clients.
If you are having issues sending emails and you get your internet through Xtra, take a look at this page on their site:
