outgoing email dropping in spam folders suddenly


I am using Centos 6 and postfix. This was working fine and I think a package or update may have broke this. I am using Virtualmin as my hosting software on my server. I have the PTR correct and an SPF record set as well. I have changed it several times trying to figure it out. I also did a header check on unlocktheinbox.com and its saying that the email is possibly 40-60% spam. Heres what I got.

postconf -n
Code:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
allow_percent_hack = no
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
config_directory = /etc/postfix

data_directory = /var/lib/postfix
debug_peer_level = 2
home_mailbox = Maildir/
html_directory = no
inet_interfaces = all
inet_protocols = all
mail_owner = postfix
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME
mailbox_size_limit = 0
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
milter_default_action = accept
milter_protocol = 2
mydomain = removed.net
newaliases_path = /usr/bin/newaliases.postfix
non_smtpd_milters = inet:localhost:8891
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sender_bcc_maps = hash:/etc/postfix/bcc
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_milters = inet:localhost:8891
smtpd_recipient_limit = 2000
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination

I know what you mean. Most dont understand the Reverse DNS spf records and all that. I can't for the life of me find out why it is doing it. I am at the point to where I just don't care lol.

As you seem 'blacklist clean' and have no obvious issues with configuration or DNS, there is really nothing you can do without some info as to what criteria the recieving server is using to classify your mail.

What reasons did this test show?
