I'm not a network infrastructure expert, but if a single piece of "new hardware" can take down not only all your POP and IMAP access but even your webmail and website, that seems like a design problem--especially if it's happened before.
I'm used to redundant connections to the net, redundant routers, redundant firewalls, redundant load balancing, etc. It's usually the guy trying to run everything out of a single rack at some co-located site (or in his basement) that has critical single points of failure such as you're describing.
In addition to sending debugging information to the hardware vendor, perhaps you need to re-visit the architecture so one piece of hardware can't create such a massive outage?
