[kronolith] Problem with reminders in 2.1

[Mark Reis]

I'm running into a problem where I'm unable to get reminders.php to send
emails. The current setup is: Horde 3.1.1, Kronolith 2.1, php-4.4.0 and
MySQL 5.0 as my backend. 

Looking at the horde log, I see:

 Apr 01 13:53:29 HORDEDEBUG [info] [kronolith] No email addresses available
to send reminder for Test to recipient(s): testuser  [on line 187 of
"/pathtohorde/horde3test/kronolith/lib/Scheduler/kronolith.php"]

This is a bit odd since I'm under the impression that I set up this address
with the from_addr preference. (I've swapped mydomain for my real domain to
confuse spambots). IMP works just fine, so I'd like to think that horde and
imp are configured correctly.

Help?
