Is SMTP to a mobile phone a fundamentally flawed way to do this?

We tend to avoid the whole SMTP mess and deliver messages to mobiles and
pagers via a modem and the provider's TAP gateway.  It works quite well with
Verizon and AT&T/Cingular, but I've no experience with T-Mobile.  It also
avoids the whole mess of failing to alert when your monitoring box has a bad
NIC, cable, switchport, etc - of course considering that you trade those for
problems with a serial port, cable, modem, or phone line...  But it gives us
a big (and perhaps false) warm fuzzy that our alerting is 'out of band'
relative to our upstream Internet connections.

The folks at Avtech have a nice index of TAP gateway numbers at

Hope you find this useful...
