What is this error?

Apr 14 18:38:11 alexcasa dovecot: child 12276 (pop3) returned error 89

I'm working with dovecot-1.0.beta7

imaps works fine

Above that error message there should be the real error message, which tells what's wrong.

But I'm guessing you haven't set pop3_uidl_format in config file.
