I have basically all the possible spam checking rules turned on in my system as my CEO complains vociferously about spam (bug surprise there). However avis is unable to email reservation confirmations to me and I need to whitelist or unblock that server. Here is the log snippet:
NOQUEUE: reject: RCPT from ccrgws006.cendantcarrental.com[18.104.22.168]: 554 Service unavailable; Client host [22.214.171.124] blocked using dnsbl.njabl.org; open proxy -- 1153750086; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<ccrgws006.boulder.mebs.ihost.com>
Is there a way to do this without turning off dnsbl? Also I think it would be kick axe to have more control over this through the admin gui...but that my two cents.
