Um, no, it can't. But that's a whole different story. Microsoft has some hard num bers about the speed of the IIS SMTP component in comparison to sendmail. I think they're in a whitepaper someone on the MS site.
That being said, I'm not a fan of exposing Exchange directly to the Internet. If for no other reason, I like to run border virus scanning (using VirusWall from Trend Micro), which I feel runs better on Unix. Even then, these systems are in the middle of the mail flow (internal relays). We use a highly locked down[1] version of OpenBSD as inbound only relays in our DMZ (they only accept and forward mail for us - they don't send mail outbound). It's a bit overkill, but we also run a lot more mail through our systems than comparible sized companies seem to do. To answer your question, however, I've not found a case where a properly tuned Exchange server fell under load, short of an outright DOS attack or mail loop. -------------------------------------------------------------- Roger D.
