Default If you "Send a copy to" an email forward it will bounce

I am experiencing a problem where mail forwarded from a mailbox using "Send a copy to" will bounce
To recreate it follow theses steps
1)Create an email forward like foo@me.com
2)Create a new mailbox like abc@me.com and in the "Send a copy to" box write in foo@me.com
3)Send an email to abc@me.com and it will bounce with a log message like this
to=<foo@me.com>, relay=dovecot, delay=0.87, delays=0.5/0/0/0.37, dsn=5.1.1, status=bounced (user unknown)
I am using postfix and dovecot

Here is my main.cf i have changed myhostname for this post
I think I only modified smtpd_recipient_restrictions and mynetworks

# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = /usr/share/doc/postfix

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.key
#smtpd_tls_CAfile = /etc/postfix/sub.class1.server.ca.pem
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = mail.me.com
alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases
alias_database = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases
myorigin = /etc/mailname

smtpd_tls_security_level = may

smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf
smtpd_client_restrictions = permit_mynetworks check_client_access mysql:/etc/postfix/mysql-virtual_client.cf
smtpd_client_message_rate_limit = 100
maildrop_destination_concurrency_limit = 1
maildrop_destination_recipient_limit = 1
virtual_transport = dovecot
header_checks = regexp:/etc/postfix/header_checks
mime_header_checks = regexp:/etc/postfix/mime_header_checks
nested_header_checks = regexp:/etc/postfix/nested_header_checks
body_checks = regexp:/etc/postfix/body_checks
owner_request_special = no
dovecot_destination_recipient_limit = 1
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
content_filter = amavis:[127.0.0.1]:10024
receive_override_options = no_address_mappings
message_size_limit = 0

I am pretty sure this is supposed to work.
Any help would be appreciated

1)Create an email forward like foo@me.com
2)Create a new mailbox like abc@me.com and in the "Send a copy to" box write in foo@me.com
This creates a mail loop which gets detected by postfix and stopped.

The message goes abc@me.com -> "Send a copy to" -> foo@me.com
foo@me.com is a forward which goes to someother@xyz.com
There is no loop.
The mail.log message is
to=<foo@me.com>, relay=dovecot, delay=0.87, delays=0.5/0/0/0.37, dsn=5.1.1, status=bounced (user unknown)

There is no loop. foo@me.com forwards to somewhere else.
The mail.log message is this
to=<foo@me.com>, relay=dovecot, delay=0.87, delays=0.5/0/0/0.37, dsn=5.1.1, status=bounced (user unknown)
