I found that the /opt/zimbra/log/zmlogswatch.out contains an error "RRDs.c: loadable library and perl binaries are mismatched (got handshake key 0xdb00080, needed 0xde00080)". Wild guess. That message generally means A dynamic library .so was being loaded into the process that was built a...

It runs as a milter I believe. Is /opt/zimbra/conf/opendkim.conf present? Does it look sane for your environment? What about master.cf? Do you see the DKIM entry. What about amavisd.conf? Is DKIM verification enabled? Ref: https://wiki.zimbra.com/wiki/Configuring_for_DKIM_Signing Generally it is fai...

Unless you removed your entry, it doesn't appear to be published via DNS from where I am. You can pull your txt record yourself and compare against what zimbra generated for you or use something like https://dkimcore.org/c/keycheck to track this down. I would start with making sure DNS looks good fo...

Which type of certificate is easy to manage, install and not complex? What is the advantage and disadvantage of OV and Multi-SAN Certificate? I have no experience with either but I have a few comments that might help you in determine what to look for. The certificate that is easiest to manage is on...

This was reported and is being tracked as ZBUG-1998 Did you get any feedback on this bug so far? Never. Not a peep. I had forgotten about this and noticed my email was readable again and thought it was a firefox update. I asked our developer this morning about the status of this and here is what sh...

It doesn't appear we have to do anything and they have backed off Jan 11 switch and have found a novel method to continue to support old android clients. Nutshell: A new intermediate will indirectly sign the current Let’s Encrypt intermediate certificate (R3). This ensures that clients that know the...

Two ways...

1) you have a blank transport file you postmapped so no lookup matches
2) you remove the transport file location and only use the ldap entry
ie) zmprov ms `zmhostname` zimbraMtaTransportMaps 'proxy:ldap:/opt/zimbra/conf/ldap-transport.cf'

With letsencrypt signing their own certificates beginning Jan 11, here is a link to a new feature that was added for acme.sh to support the preferred chain should anyone need to revert back to IdentTrust intermediate signed (very old android clients) or test early with the ISRG Root X1 signed before...

Should be able to do this with transport maps. Not tested but it would go something like this. Note: put the transport file where you think it makes the most sense for you and call it what you want. Could be in ~zimbra/common/conf with modern versions of Zimbra since that is where main.cf and master...

I have one of our web developers looking at the js now to see if we can come up with a quick fix. The quick fix is to restore /opt/zimbra/jetty/webapps/zimbra/js/MailCore_all.js and .zgz from P15. (and either flush browser cache, or bump zimbraCacheBusterVersion and restart mailboxd.) Thanks again ...
