In my experience the Zimbra dkim tools work fine, but...

The dkim dns record is longer than most dns providers can host in a single record, and each provider has their own method for splitting the record.

I suspect this is a dns, not Zimbra issue.

Hope that helps,

Hi Thanks for the link, this will be useful! I need to read through that, but a quick search i don't see anything about a checkbox. Have i been dreaming?

Hi, Thank you very much. Now users are able to access their mailboxes via our MTA hostname, prodmta.domain.colo. I just confused with the parameter "Web mail MTA Hostnames", which set localhost on port 25. What the hostname should it be prodmb.domain.colo(Mailbox hostname) or prodmta.doma...

I much prefer the Linux package dnsmasq over Zimbra's dnscache package.

Hope that helps...

Please go the blog post on my web site to fill out the form and I will send it to you. Hosting on AWS is very different than h...

After making the change suggested by Zimbra Support and restarting mailboxd, I have no more CompoundCachingTier errors.

I've suggested to Zimbra Support that the default value for zimbraImapInactiveSessionEhcacheSize be increased to 100MB for new Zimbra installs.

Hope that helps others,

Those variables are available in Global Config, so if you set them there they will be inherited each time you make a new domain, and then you won't need to set them on a per-domain basis -- except to change them from the defaults. Hope that helps, Mark zimbra@zimbra:~$ zmprov desc -a zimbraPublicSer...

I committed to updating this thread when I heard back from Zimbra Support definitively... After reviewing my situation, Zimbra asked me to run: zmprov ms `zmhostname` zimbraImapInactiveSessionEhcacheSize 104857600 on all my mailbox servers, and then restart the mailbox service. The variable is origi...
