NZ ISP Xtra are going to start blocking SMTP Traffic on port 25 from April 2006 onwards.

Those of you who send your mail out via your kiwihosting account will most likely be effected and will need to change your email port from 25 to 2525 in your email configuration.

Alternatively, and we noramlly recommend you set your email client up this way, just change your outbound mailserver to use your Xtra assigned mailserver instead and this should prevent any problems when they start blocking the port.
