This is something that's always amused me - if I've got an email2SMS service set up, how do I get the SMS to tell me that my mail server or mail provider or connectivity's gone down?
Indeed ...
Personally I use SMS_Client to send SMS directly via the POTS for critical alerts.
GSM modems in the form of USB sticks are extremely common around here (don't know about the US, but I'd suspect you have them also). Stick one or two of those on your Xymon server, and add a bit of software to interface it via Xymon's "script" alert mechanism - voila, alerting that doesn't rely on your Internet-connection or the availability of a mailserver.
I use the "smstools" package from Debian Linux to manage the GSM modem. Works fine, only problem is that the modems have a bad habit of going into a "sleep" mode that requires reloading the driver before they wake up. Probably a specific hardware issue with these modems, but since I have a work-around it isn't much of a problem.
For bonus points I interfaced with Postscript for a home-made mail->sms gateway.
