I did not spend more than 2 minutes looking for an answer, so please excuse my ignorance in case I missed the obvious: Where do I send (suggestions for) corrections of certified Zimbra Wiki articles? In https://wiki.zimbra.com/wiki/Performance_Tuning_Guidelines_for_Large_Deployments#MariaDB.2FMySQL ...

Are you using POP or IMAP? If IMAP, it might be a problem on the Mac side. Open a Terminal and have a look at your IMAP-folder (something like /Users/your_user/Library/Mail/V2/IMAP-your_user@your_server.domain.tld). If you find a non-empty folder named ".OfflineCache", stop Mail.app, move ...

From my personal experience with Zimbra 8.5.1 "smtpd_recipient_restrictions.cf" will be overwritten as soon as zmconfigd rewrites its configuration files. For example changing a DNS blacklist will trigger this. I put my changes into "smtpd_recipient_restrictions.cf.in" which shou...

With Zimbra 8.5.1 I have to check for 2 more headers to recognize genuine mails from my server. Do you see these in your log files? Received: from zimbra.greenfieldin.org (localhost.localdomain [127.0.0.1]) Received: from zimbra.greenfieldin.org (LHLO zimbra.greenfieldin.org) (10.16.2.28) As a refer...

A word of caution about net.ipv4.tcp_tw_reuse=1 net.ipv4.tcp_tw_recycle=1 My server is behind a firewall and people using the webinterface had lots of timeouts when these settings were in effect. I am no expert when it comes to network technology, it's just an observation that without these settings...

I assume you have split DNS set up. Would it be feasible to change the A name for your DMZ zone to "zimbra.<MYDOMAIN>.de" and introduce a CNAME of "zimbra.dmz.<MYDOMAIN>.de" an also change /etc/hosts on your Zimbra server to contain zimbra.<MYDOMAIN>.de?

My mistake, I didn't realize I was able to edit my own posts by using the link "More". Scratch the third point from my wish list.

I solved my problem with header checks. With Zimbra 8.5.1 I had to add these checks to /opt/zimbra/conf/postfix_header_checks.in so they'd survive the rewriting of the postfix configuration by zmconfigd. The checks reject a bounced mail if it's missing the headers a mail originating from my server h...
