Postfix RBL lists debug ?

[RaNd]

In our older postfix mail server we could see the connections that were dropped using RBL check lists, is this possible in Zimbra ?

Found :

Making Postfix daemon programs more verbose

Append one or more "-v" options to selected daemon definitions in /etc/postfix/master.cf and type "postfix reload". This will cause a lot of activity to be logged to the syslog daemon. For example, to make the Postfix SMTP server process more verbose:

/etc/postfix/master.cf:
smtp inet n - n - - smtpd -v


Will this work ??

Yes, however with some cavets.
1) You'll need to edit /opt/zimbra/conf/main.cf
and
2) We don't recommend editing the main.cf file. Any changes you make will not survive an upgrade.
