This problem has been fixed in Qpopper 3.0.1b2, which is now available. Note that the problem does not occur on Solaris systems (which use Content-Length), nor on systems which use mail or certain other local delivery agents. I was able to reproduce it on Linux using mail.local. Also, note that the patch supplied in the email message may not function correctly and may cause messages to not be recognized.
