alert MAIL FORMAT=SMS generates large message

I have the following alert in hobbit-alerts.cfg

MAIL FORMAT=SMS phonenumber at domain.com  COLOR=red REPEAT=20

RECOVERED

The alert action happens when it's supposed to, but the admin does not receive the special tiny-size SMS. Instead he receives the large-size email that MAIL FORMAT=TEXT would generate, which his phone service splits up into four separate messages. Has anyone else seen this? Is there something subtle I'm doing wrong?

Thanks, David
