Regarding the issue of e-mail from @u addresses not being delivered to some @un addresses

We apologise for any inconvenience this may cause.

Due to an update to the @u email system, emails from @u to some @un addresses are not being delivered.
We are currently taking action and monitoring progress.
It will take a few days to reflect on this, so we would appreciate it if you could wait a little longer.

Thank you for your continued support.
