zimbra: pushing banned contents in email

got BANNED CONTENTS ALERT from zimbra's content checker after receiving an .exe file in email. it is a great email security feature that blocks unwanted contents, but what if you are expecting the banned content?

you can push the email manually from the shell!

1. take note of the internal reference code of your email (highlighted below):

your blocked email should be /opt/zimbra/data/amavisd/quarantine/banned-<reference code>

2. manually push it by issuing:
$ /opt/zimbra/bin/zmlmtpinject -s <source email> /opt/zimbra/data/amavisd/quarantine/banned-<reference code> -r <recipient email>

then wait for it in your inbox ;)
