Security and patch applies

We need someone with very good knowledge for dolphin to apply the last security patch to 2 of our dolphin web sites. This should be a simple apply of the latest security patches for dolphin and maybe some general control to be sure all is in order.

Despite the fact we are using it almost for testing activities we are facing problems with people sending spam emails from them.

Appreciate your reply with quotations ASAP.

Thanks
