    Default Is there a limit on number of RBLs

    Is there a restriction on the number of RBL's you can setup? Every time I run this shell script,
    I only get abuseat.org and spamcop.net as RBLs in the postfix main.cf file. I really need the other ones.

    #!/bin/sh
    # set Zimbra RBLs
    /opt/zimbra/bin/zmprov mcf zimbraMtaRestriction reject_invalid_hostname \
    zimbraMtaRestriction reject_non_fqdn_hostname \
    zimbraMtaRestriction reject_non_fqdn_sender \
    zimbraMtaRestriction reject_unknown_client \
    zimbraMtaRestriction reject_unknown_sender_domain \
    zimbraMtaRestriction "reject_rbl_client xbl-xbl.spamhaus.org" \
    zimbraMtaRestriction "reject_rbl_client bl.spamcop.net" \
    zimbraMtaRestriction "reject_rbl_client cbl.abuseat.org" \
    zimbraMtaRestriction "reject_rbl_client rbl.mydomain.com"
    /opt/zimbra/bin/zmprov gacf | grep zimbraMtaRestriction

    The funny thing about it, is that the last line of the script does verify my settings were
    set somewhere in Zimbra.

    well instead of "xbl-xbl.spamhaus.org" try just xbl.spamhaus.org or zen.spamhasu.org (which combines sbl/xbl/pbl)

    I use: zmprov mcf zimbraMtaRestriction reject_invalid_hostname zimbraMtaRestriction reject_non_fqdn_hostname zimbraMtaRestriction reject_non_fqdn_sender zimbraMtaRestriction reject_unknown_sender_domain zimbraMtaRestriction “reject_rbl_client dnsbl.njabl.org” zimbraMtaRestriction “reject_rbl_client cbl.abuseat.org” zimbraMtaRestriction “reject_rbl_client bl.spamcop.net” zimbraMtaRestriction “reject_rbl_client dnsbl.sorbs.net” zimbraMtaRestriction “reject_rbl_client zen.spamhaus.org”

    Careful with reject_unknown_client & reject_unknown_hostname they can block more than you think sometimes...

    Default Custom RBL's not working

    It seems that Zimbra is not allowing me to specify an rbl list that I want to use.

    rbl.pfinders.com

    Is there a restriction on only a few known rbl lists?

    This custom rbl list is one that I maintain myself.

    There's no restriction in Zimbra on the RBL that you can use - it wouldn't make sense for us to do that.

    No, it hasn't. I've just been looking at it.

    As discussed in RBLs restricted? there actually IS a restriction on the RBL lists you can use. You need to edit /opt/zimbra/conf/postfix_recipient_restrictions.cf and add all lists that you want to use and then reapply your configuration. It should now add the lists that you want.
