Re: How Disable Antivirus and only use spamassassin?

The reason I like to keep Zimbra's AS/AV in place even when you have inbound and outbound AS/AV protection (from IronPort, Mimecast, Barracuda or similar) is that Zimbra routes email for any domain it hosts entirely internally. So, if one mailbox starts emailing malware to every other mailbox on the...

Re: CVE-2019-9670 being actively exploited

Re: Thoughts regarding X-Originating-IP headers

Interesting old discussion on this here:

Re: Thoughts regarding X-Originating-IP headers

Years ago I would turn off X-Originating-IP, but now I keep it turned on because It is necessary for the IP blocking capability of DoSFilter, which I find very useful. The false positives in my experience are all from ZCO users on dynamic and other IP addresses that SpamAssassin wants to block/score...

Re: Zimbra 8.8.15 RC1 Released (IMHO)

Sebastian,

You are NOT hijacking the post at all.

It’s good to have one or more threads for new releases where early adopters can post there successes and challenges, so that others can adopt their workarounds or upgrade with better confidence.

Thanks for the detailed posts!

Re: Zimbra 8.8.15 RC1 Released (IMHO)

Sebastian, Thanks for posting your upgrade experience. On the documentation discrepancies, I would ask Rick (his nickname is "The King" because, well... he is!) if he needs you to make a separate support ticket to get those addressed. Regarding the libreoffice-headless "missing" ...

Zimbra 8.8.15 RC1 Released (IMHO)

Zimbra released 8.8.12 today. The Release Notes are here: https://wiki.zimbra.com/wiki/Zimbra_Releases/8.8.12 IMHO, 8.8.12 is effectively 8.8.15 LTS Release Candidate 1.
