The trouble with SMTP gateways, though, is that (a) messages can get held up for long periods in queues, with no timely notification of the delay to the system originating the page, and (b) if you can send mail to your pager, so can ten thousand evil spammers.
The other thing to remember is that depending on your application, an SMTP gateway may not be reliably reachable. If you're trying to page people when devices/providers/cables/whatever fail, the gateway wont receive the page if a cable/switch/router/media converter/provider between whatever's speaking SMTP on your network and the gateway has blown up. Depends on your requirements, and this can be worked around anyway (two monitoring points, etc). Michael
