Auto-Reply Not working

Hello,
I've instaled OTRS otrs-2.0.2-01-win32.exe on a
Windows XP machine. SMTP seems to work to manually
reply to emails received via POP3. However, the
auto-reply does not seem to work.
I checked the otrs.log file and apparently the system
appears to have logged the instance of sending the
auto-reply. But in fact, nothing is actually sent.
See log below:
