Is the CPU busy for 2 minutes? This sounds like a network-related
misconfiguration, like a DNS lookup that is timing out. Are you using
any DNS-based blacklists from MIMEDefang?

Not really... If you can capture the message by keeping the spool
directory around, you can run mimedefang.pl by hand.
# Undocumented hack to prevent deletion of mdefang-* directories
# Wait for problem message
Once you have the problem message in an mdefang-xxxx directory, you
can run mimedefang.pl by hand like this:
rm -rf Work
You can use whatever Perl debugging facilities or system-call trace
facilities you like to figure out what the last line is doing.
