Re: DKIM Signature Body Hash Does Not Verify
I think you can chalk this up as a false positive on MxToolbox's part. Same chatter on the Office 365 forums about this, so it is not Zimbra-specific, and as Phoenix said, it does not impact email delivery at all. Hope that helps, Mark Thanks Mark....yes looking like the case. I do have some issues...

Re: DKIM Signature Body Hash Does Not Verify
I've just sent them an email to their test account at ping@tools.mxtoolbox.com - I see the same failure as you and yet I can send mail anywhere (including google, Yahoo etc) without that problem occurring. Well, I'm somewhat confused by the results from the MXtoolbox site as they are somewhat unexp...

Re: DKIM Signature Body Hash Does Not Verify
I wouldn't have thought this would be related to the ZCS version but I always like to keep on the most recent release. I'm not really sure if Opendkim had any problems similar to this but I never had any problems with it but that was a few years ago. :) On Rspamd whats the eta for integration? And ...

Re: DKIM Signature Body Hash Does Not Verify
2048-bit signature standard. Maybe try lesser just for kicks? Perhaps version related? Release 8.8.9_GA_2055.RHEL7_64_20180703080917 RHEL7_64 FOSS edition, Patch 8.8.9_P10 w/ Zextras Installed. DNS checks out, on AWS R53 and all is well in that regard. Same format as other domains in same environ. B...

Re: DKIM Signature Body Hash Does Not Verify
Do you get the same result when it's sent to another test site (or google, perhaps)? Have you tried regenerating you DKIM signature for that domain? Its the only domain that returns no result. I did try regen the DKIM for the domain after my last message. Same situation. Its strange this, nothing r...

Re: DKIM Signature Body Hash Does Not Verify
And another strange related thing...I get no response when testing the validity of the DKIM sig against the server
This specific domain returns crickets, nothing, yet other domains do.

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...
