Different RBLs in different places

[Paolo C]

Hi everybody,
this is my first post.

I'm using the OS edition, version 5.0.2 on Ubuntu 7.10.
Configuring Zimbra to use postfix-policyd (following this article Postfix Policyd - Zimbra :: Wiki)
I noticed that there are 3 different RBLs lists in
1) postfix/conf/main.cf (smtpd_recipient_restrictions)
2) conf/postfix_recipient_restrictions.cf
3) zmprov gacf (zimbraMtaRestriction)

Which I have to modify if, for example, I want to add another RBL?

Thanks
(and sorry in case the question is trivial).

Use zmprov, that will ensure your modification doesn't get overwritten.

Thank you.
When I use zmprov, the main.cf e postfix_recipients_restrictions.cd are not modified. Are they ignored? or RBLs are used by different component of Zimbra?

I am no postfix expert, but if it behaves the way other components (for example SpamAssassin) do, then there is a hierarchy of config files that can affect the program's behavior. In the case of SpamAssassin, the same configuration settings (scores for various types of bad behavior) that are set by standard in /opt/zimbra/conf/spamassassin/50_scores.cf can be overridden by the same syntax but different settings in local.cf which is in the same directory. I presume something similar happens here.

But as Bill pointed out and I will reiterate, if you make changes at the config file level, they will likely not survive an upgrade, as upgrades re-write the standard files. If, on the other hand, you configure your settings with zmprov, these settings do survive an upgrade and continue to work. This is a Good Thing(tm). . .

I tried the Good Thing, but it has no effect (I checked mail.log).
When I modified the file postfix_recipients_restrictions.cf, the file main.cf was consistently modified by some component, and I can see that the RBL just added is used (from mail.log).

edit: ok, the answer is here: Configuring and Monitoring Postfix DNSBL - Zimbra :: Wiki
I have to do both things.

Thank you phoenix and dwmtractor.
