1) You can obtain this by modifying the master.cf.in.
- On ZCS v8.6 and Old: Modify
"/opt/zimbra/postfix/conf/master.cf.in", go to the smtpd line and at the end of the line add -vv
smtp inet n - n - - smtpd -vv
- On ZCS v8.7.x and Above: Modify
"/opt/zimbra/common/conf/master.cf.in", go to the postscreen and smtpd lines and at the end of the line add -vv
smtp inet n - n - 1 postscreen -vv ... smtpd pass - - n - - smtpd -vv ... smtp unix - - n - - smtp -vv ... 465 inet n - n - - smtpd -vv ... submission inet n - n - - smtpd -vv
