Hello all!

I am new to Zimbra administration because the old IT guy left and now I am doing my best to fill his shoes.
The were big shoes! So any and all help is appreciated.

As the title says, I am trying to configure Zimbra to remove the original message from 'bounced' emails that are sent to invalid addresses in our domain.

We want to do this because we have become a backscattering target. We're fine with returning a notice that the target address was not found, but we DON'T want to return the original body - lest it be some nasty spam, which would turn us into nasty backscatterers!


Here's a sample of the Zimbra log (/var/log/zimbra.log) for what happens when I send an email from my gmail account to an invalid account in our domain:

Thank you SO much in advance. I'm very thankful for these forums because I'm utterly lost at the moment - fingers crossed!

Cheers
