Hi

i dumped dovecot POP3 because of problems with mbox file locking that never
got answered.
i use 4.0.8 (will have to check more often on new releases).

quite a few customers have over 30MB of mail and i have had nothing but
praise since i moved to qpopper from those big users who had locking issues
all the time.
