So the site software update is complete! It took longer than we thought but the site is now live so come and have a look around http://myforum.co.uk/ We still have a few things to sort behind the scenes but all should be working.

Please let me know if you have any problems or notice any error so i can sort them ASAP!

Have fun ;)

Was it one person or a bunch of people?

That error just indicates that the mail system rejected the mail, but it doesn't give a reason why. If it's just one user, you can likely disregard it, but if it's a lot you definitely need to try to figure out what happened. There should be logs in your /var/log/maillog file, but you'd need to be root to read it (so if it's not a VPS, your host would have to help you).
