Re: Zimbra and Openstack

We have Zimbra running in OpenStack and also oVirt using GlusterFS. Performance is great and have presented no issues beyond typical config work. We are now experimenting with Zimbra in DC/OS > oVirt and also have great results so far. I plan to post detailed results after we wrap up!

Re: Which DNSBL lists are you using?

I am using b.barracudacentral.org and zen.spamhaus.org, but we are getting blocked from using zen.spamhaus.org periodically. I would suspect that it is due the fact that we are exceeding their low volume limits for free use. I am pretty sure that it is because we are using Google DNS for our 3rd an...

Re: Multi-Server Install - DNS Configuration

Hi, Hi All.... In a multi-server install does the Zimbra Proxy route all traffic up and down from the other Zimbra services? More specifically, in external DNS, does the Zimbra MTA/Mail need to be listed with an A and MX record or only the Zimbra Proxy? My current thinking is that only the Zimbra P...

Re: Multi-Proxy Setup - SNI SSL

I've managed to answer my own question.... Hopefully it holds up in an HA environment. With assistance from Ansible it very well should. Any correction/improvement to this model from the Zimbra world is very much welcomed! - Each Proxy (2 proxies are running in my use case) has been configured with ...

Re: Certificate on admin portal

OK, and how does this help me? can you explain me what I should do to fix this? Hans There are typically 2 methods used when securing server(s) and domains. One is a general commercial SSL for the server(s) itself, as shown in this DigiCert guide -https://www.digicert.com/csr-creation-ssl-installat...
