Error: trying to talk to myself?

[Oliver Xymoron <oxymoron@waste.org>]

I've just gotten a slew of different error messages like these.. A 
similar message appears in my logs. This was after rebooting my system to 
for a quick kernel upgrade - I manually started zmailer after things 
looked good. Any ideas?
