It appears that dbmail-pop3d is sending its log stream to the client, instead of to the log file.
Tested with current CVS, and TRACE_LEVEL = 5, the following transcript was generated. I'm pretty certain that the debugging output is not a valid pop3 response. [EMAIL PROTECTED]:/etc/postfix$ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to 127.0.0.1.
