Known problem upstream. Either stick with dovecot-2.0.15 for now -which has a security bug 390887 though- or preferably migrate away from vpopmail. It is nothing but trouble.
thanks, then i will stay with 2.0.15. getting rid of vpopmail is not an option now. I would have to start from scratch with m yvirtual mail hosing system which is based on netqmail. I only know vpopmail to do virtual mailhosting based on netqmail.
