yg harus dilakukan adalah mengecek message id tersebut dengan command postcat

#postcat /opt/zimbra/postfix/sbin/postcat /opt/zimbra/data/postfix/spool/deferred/1/128F5180EE9701

perlu diketahui, jika message id berawalan

1 = /opt/zimbra/data/postfix/spool/deferred/1/
2 = /opt/zimbra/data/postfix/spool/deferred/2/
3 = /opt/zimbra/data/postfix/spool/deferred/3/
9 = /opt/zimbra/data/postfix/spool/deferred/9/
dan seterusnya.

maka hasilnya terlihat, selanjutnya jika alamat email terlihat, maka lakukan disable / closed alamat email tersebut agar tidak melakukan broadcast
