Default Undelivered Mail Returned to Sender

Hi,
I've been getting THOUSANDS of emails that says "Undelivered Mail Returned to Sender". Last weekend I got like 24k+ of mails of these things. Most of them has nothing inside it when I open it, it doesn't even have details on it's subject headers. I tried to do some research for prevention of spam emails for my Postfix's main.cf, but I still get these emails. Besides this, I also get emails mostly from a brazilian domain..some of them always mention "Bradesco" which I don't know what that is. And one last weird thing that happens to my mailbox..when I try to send a test mail to my email, I receive it and it seems to look normal in my inbox.. but when I open it, it's a whole different email which isn't the one I sent to myself.

My mailq also has been always filled with tons of these mails that delays receiving/sending of "real" emails aswell..

I hope you guys can help me on this..it's been a month and it's driving me crazy. I'm kindof a novice when it comes to this, but I'm willing to learn. My email has catchAll enabled because it's a 'postmaster' account. Thanks in advance.

Here's my main.cf
Code:
myhostname = mail.mydomain.ph
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = $mydomain
mydestination = /etc/postfix/local-host-names
relayhost =

smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
virtual_maps = hash:/etc/postfix/virtusertable
#virtual_alias_maps = hash:/etc/postfix/virtual
mydomain = immigration.gov.ph
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_data_restrictions = reject_unauth_pipelining, reject_multi_recipient_bounce, permit
smtpd_helo_restrictions = reject_unknown_helo_hostname
smtpd_sender_restrictions = reject_unknown_address, reject_unknown_sender_domain
maximal_queue_lifetime = 1d
delay_warning_time = 0h
smtpd_helo_required = yes
disable_vrfy_command = yes
Kindly,
DJ Delos Santos
