[horde] Getting the following mail - possibly due to some saved calender event

[ANANT S ATHAVALE]

Due to the cron for  /usr/bin/horde-alarms

getting the following mail to root..

Can anyone tell the reason and under what circumstances it can happen  
(any mistake in configuration?).  Why default domain doesn't get added?

Using HGWE 5.2.20

Regards,
ANANT.
