I noticed on my FreeBSD test system, that the qshape program is
not installed when installing Postfix from ports. If you do not
have it on your system, I suggest you install it. It comes with
the Postfix source code (in the /auxiliary/qshape/ directory),
so you may need to download that if you do not have it. We obtain
the source code here solely to obtain the qshape.pl program.

This tool can help you determine which queues the mail is bunched up
in, and what domains the mail is to (or from). The 'qshape deferred'
and 'qshape -s deferred' will show items in the deferred queue for
example.

Here are instructions to obtain the qshape.pl program. Before you
do this, run 'qshape' to see if it is already installed.
You can change the Postfix version number here if desired to your
currently installed version. To see what version of Posfix you are
using, use 'postconf mail_version'.

cd /usr/src
wget ftp://postfix.mirrors.pair.com/offic...x-2.2.5.tar.gz
tar xzvf postfix-2.2.5.tar.gz
cp postfix-2.2.5/auxiliary/qshape/qshape.pl /usr/local/sbin/qshape
chmod +x /usr/local/sbin/qshape
cd
rehash

For instructions on the use of qshape, see:
http://www.postfix.org/QSHAPE_README.html

Is your final destination server bouncing messages back to relay1
(and not the other servers)? In general, are you using relay1 for
any outbound mail? Is amavisd-new refusing connections?

Essentially, we are trying to gather more information on what the
source of the problem is.

BTW, manually flushing the deferred queue should actually slow things
down, because you are making Postfix (and amavisd-new) work harder than
usual.
