It works fine for an our small company but we have a problems.
zimbra Release 8.0.4.GA.5737.UBUNTU12.64 UBUNTU12_64 FOSS edition.
I have turned on RBLs, because we have many spam messages. After that we have a fine result with it but some our external users can't send any e-mail via their MUA (iPAD) because zimbra reject it with a message like this:
So, I have the following records in zimbra.log about it:
"relay denied bla-bla-bla".
I have a confuse with ip 10.52.114.117 - I think it is an ip for internal NAT 3G clients.
Sep 27 13:47:40 mail saslauthd: auth_zimbra: myuser auth OK
Sep 27 13:47:40 mail postfix/smtpd: NOQUEUE: reject: RCPT from unknown[184.108.40.206]: 554 5.7.1 Service unavailable; Client host [220.127.116.11] blocked using cbl.abuseat.org; Blocked - see http://cbl.abuseat.org/lookup.cgi?ip=18.104.22.168; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<[10.52.114.117]>
Sep 27 13:47:41 mail postfix/smtpd: disconnect from unknown[22.214.171.124]
It is obviously for me about the user "myuser" ip is in The CBL db. It is OK, because the user use a public 3G network...
How to tell zimbra to disable RBLs check for AUTH users? Or apply another solution...
