Installing a commercial SSL certificate in Zimbra

I installed a commercial (free) SSL certificate from Startcom SSL in Zimbra. I basically followed this, except the java keytool thing. I don't know why that is necessary... I did this on Zimbra 6.0.10_GA_2692.UBUNTU8_64 UBUNTU8_64 FOSS edition. Read More »

Disabling exim port 25 listening when zimbra is installed

Edit: This doesn't work anymore I don't think, because more modern versions check for SMTP conflicts and don't allow this. Read More »

Zimbra has no shutdown init script on Debian and Ubuntu

There is a K01zimbra in rc6.d for reboot, but not in rc0.d. See this bug report I made. Read More »

Zimbra dependancy on ‘file’

Zimbra has a dependancy on 'file', which the installer file won't check for. It is also a WONTFIX bug, so beware: install file(1)! If you don't, mails get stuck in queue because amavisd won't run.

Making mysqldump work on a zimbra installation

Zimbra installs its own mysql and there is no workable mysqldump command. There is a mysql command wrapper script (/opt/zimbra/bin/mysql) that loads an environment to set password and such, but there is no such thing for mysqldump. I copied that wrapper script to /usr/local/bin/mysqldump so that user zimbra can no run mysqldump. This is it: Read More »

Disable Zimbra’s duplicate mail detection

Zimbra can discard duplicates of incoming mail. This has certain advantages, but for us, where different people use the same account with different identities, this prevents a message from being delivered to multiple virtual inboxes. Read More »

Lowering Bayes score for Zimbra’s Spamassassin config

The Spamassassin config in Zimbra has a very high default score for bayes matching of 99, 95, 90, etc, percent. A mail with subject and body "test" or "asdfaewf a" is often marked as 99% bayes, even though the spamfilter has seen no training mail. This is absurd. Read More »

Configuring fetchmail to deliver to Zimbra with custom header added

I needed to fetch mail from a POP3 account and deliver it to a Zimbra account. Because I'm doing this for multiple POP3 accounts, I want to add a header which I can use in Zimbra to filter. This is what we made: Read More »

Fixing spamassassin rule in Zimbra

Spamassassin has had a bug for a while, marking any mail from 2010 and later as spam because it's from "far into the future". This was very crudely done as this regexp: /20[1-9][0-9]/. Because of that, almost all mail from 2010 onward is marked as spam. Read More »

Set proper origin domain for Zimbra server

(This turned out not to be how I fixed it. I just configured exim and /etc/mailname as I do always and that fixed it. However, exim does not run as the SMTP server listening on port 25, that is the postfix installed by Zimbra. I don't know how and if this exim configuration conflicts with zimbra.) Read More »
