I have also had problems with adding zen.sa - sbl works fine though! Is there a specific set of rbls that zimbra will allow?
Running NE (4.5.6_GA_1044.UBUNTU6) on ubuntu 6.06

I become the zimbra user, then:

zmprov mcf zimbraMtaRestriction reject_invalid_hostname zimbraMtaRestriction reject_non_fqdn_hostname zimbraMtaRestriction reject_non_fqdn_sender zimbraMtaRestriction "reject_rbl_client zen.spamhaus.org" zimbraMtaRestriction "reject_rbl_client sbl.spamhaus.org"

(yes, zen and sbl should not both be in the list, but this is to prove a point.)
Now wait a few moments for zimbra to update the postfix config, just check that zimbra knows about it:

zmprov gacf | grep zimbraMtaRestriction
zimbraMtaRestriction: reject_invalid_hostname
zimbraMtaRestriction: reject_non_fqdn_hostname
zimbraMtaRestriction: reject_non_fqdn_sender
zimbraMtaRestriction: reject_rbl_client zen.spamhaus.org
zimbraMtaRestriction: reject_rbl_client sbl.spamhaus.org

So zimbra has accepted the changes. Lets see what postfix thinks:
postconf | grep smtpd_recipient_restrictions
smtpd_recipient_restrictions = reject_non_fqdn_recipient, permit_sasl_authenticated, permit_mynetworks, reject_unlisted_recipient, reject_invalid_hostname, reject_non_fqdn_hostname, reject_non_fqdn_sender, reject_rbl_client sbl.spamhaus.org, reject_unauth_destination, permit

Only sbl.spamhaus.org is added! Whats going on here?

Of course previously I added just zen.sa and wondered why nothing seemed to be happening, and postconf would not show any changes at all. It only seems to accept sbl.

Is this by design (only a predefined set of rbls are accepted), or is this some kind of wierd bug? Searching bugzilla for zen.spamhaus.org and spamhaus.org showed zarro bugs.

Any ideas?
