    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.

    # Uncomment the next line to generate "delayed mail" warnings

    message_size_limit = 0

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

    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)
