I am having email delays that are over two hours long. I can not figure
this out but `qshape` shows thousands of messages in the mail queue, but
`mailq` says the that /var/spool/mqueue is empty. I have rebooted
several times and flushed everything I can. Anymore ideas for me?

When faced with a clogged toilet, clear the blockage first,
then flush. Flushing the postfix queue without fixing the
underlying problem is unlikely to help, and will probably make
matters worse. ditto for rebooting.
My first guess is that you're running the sendmail(TM) mailq
command rather than the postfix mailq command. Uninstall
sendmail to fix this, or try running "postqueue -p"
My second guess is that your queue is clogged with thousands
of messages to unknown recipients that postfix is working hard
to return to the forged sender address. Accepting mail to
unknown recipients will bog down your server and turn you into
a backscatter source; your server will eventually be
blacklisted for this. Make sure your system does not accept
mail to undeliverable or invalid recipients.
For definite answers rather than guesses, please provide more
information; postconf -n, qshape, mailq, log entries of
delayed deliveries, etc.
