Mcafee Webshield email scanning is pants

In order to move our existing internet connectivity from leased line to broadband without disrupting email whilst dns changes take affect we're putting in a mail relay on the local lan and the easiest way to do this was to use Mcafee's email scanning server and use this as a relay. The problem is that the software is pants and everytime you save the configuration of the server it crashes and the machine has to be rebooted.
The hotfix that I had to install also had no installation routine - you had to download a zip file,extract it, determine that you needed to read hotfix8.txt which prompted you to stop the services, copy the files across and then restart them. Now surely it can't be that hard to write an install script to do that?
I really hope this is not an indication of the stability of the corporate version that I might have to rollout in the near future :-(
