I'm also seeing this, but only on one server. Other mailscanners are working
correctly, and they are using the same versions. I really do not know what the
problem is. I compared all the config files, etc but they are all the 
same. The
only difference is that the 'problematic' machine is Fedora Core 3, and the
other 'working' machines are RHEL 3 and Fecora Core 4.

Though, by us the email seems to be delivered, but they're still 
standing in the
mqueue.in/ folder.

If there are a lot of mails in there, the load of the mailserver keeps getting
higher and higher, so I copy the folder to an backupfolder and empty the
/var/spool/mqueue.in/ folder, so the load returns to normal and I have 
still an
copy of the email (just in case).
