Very strange. Are you using Dovecot from etch or a version from
backports.org? I suggest you use the latter since etch's version has
known problems. (I haven't heard of this problem, though.)
Still, I am having trouble to imagine how Dovecot might responsible for
this strange behaviour. I'd try another client and see whether the
problem persists.
Another point-of-failure might lie in your mail delivery program. How
are mails delivered to your maiboxes?
