Good afternoon

I can find a contact in the contact email me.

Ex:

[Root @ lnxmail scripts] # /opt/zimbra/bin/zmmailbox-z-m efcunha@xxx.xxx.br gact | grep "wilcy@xxx.xxx.br"

this above command returns me the email below:

email: wilcy@xxx.xxx.br

Is there any way gave delete this contact using email as a reference?
