Re: zmprov issue - 8.8.15

An update for 8.8.15 - this has changed a little, and when updating from 8.8.12 I ran into this issue with my CACERT certificate for the first time. The CACERT certificate is called "commercial.crt" and is in the "commerical" directory according to the long-standing howto, so: As...

Re: Unable to update to 8.8.12p5 on Ubuntu 14

Same problem for me. No solutions found yet. And for me on Centos 7 during upgrade from latest 8.8.12 to 8.8.15 error: Failed dependencies: zimbra-timezone-data >= 1.0.1+1565604774 is needed by (installed) zimbra-patch-8.8.12.1566472978.p5-1.r7.x86_64 Package mgt reports that 1.0.1+1565604774-1.r7 ...

Re: Block SPAM email from new domains?

Thanks for the detailed info. The key issue I have is that SEM_FRESH and related lists don't appear to pick up any of the problem domains (tested 3 recent ones), so that logic isn't currently useful. I will test immediately when I get the next "same day" example to be sure though. I don't ...

Re: Block SPAM email from new domains?

Thanks. One does at least know a DNS record exists if SPAM comes from that domain and passes DKIM. The example I gave lloydsbankonline.uk was registered (and suspended - the record is still there) on 14-Nov-2018, but doesn't appear in SEM-FRESH15 or SEM-FRESH30, or SEM-URIRED (and also no history) w...

Re: Block SPAM email from new domains?

Thanks for all the feedback.
When I run a 'whois' on my own domain, I can immediately see "Creation Date: ...." in standard ISO 8601 format.
So I should be able to check that in an SA rule ...
I was hoping someone might have written the code in the dim-distant-past ?

Re: Block SPAM email from new domains?

Obviously not whitelisted by me - domain created yesterday, yet in the headers: X-Spam-Status: No, score=x required=9.4 WHITELISTED tests=[] autolearn=unavailable and DKIM sig: DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=key; d=lloydsbankonline.uk; h=Mime-Version:Date:To:Subject:From:Conte...

Block SPAM email from new domains?

A recent problem seems to be caused by domains maliciously registered very recently, looking very similar to real online banking domains, often registered the the same day as the received SPAM, with all the correct DKIM keys etc (often at Godaddy), then used to SPAM/Phish. Issues are: By default Zim...

Re: Upgrade from 8.6 to 8.7.11 - java.security.cert.CertificateException with CACERT certificate

Thanks for your reply. In the end I gave up on that upgrade, reverted to my 8.6.0 backup container, re-did the upgrade procedure in a different order, this time it's OK. For the benefit of others, I think I may have mistakenly done the proxy cipher upgrade before the main upgrade procedure, though I...

Re: Bug: zmconfigdctl fails when "which" is not installed

Yep, I found that too.
Also you might find other basic utilities like "less" and rsync missing, e.g. in a container environment.
If less is missing, some perl modules can't be compiled.
