Re: Unable to block an entire domain with Zimbra 8.7

I was able to solve this. I had to add zimbraMtaSmtpdSenderRestrictions zmprov ms 'yourzimbraservername' +zimbraMtaSmtpdSenderRestrictions "check_sender_access lmdb:/opt/zimbra/conf/postfix_reject_sender" This will automatically update the postconf and that will not disappear after reboots...

Re: <SOLVED> Blocking incoming emails for one recipient domain

I would like to re-address this thread. These working on a Zimbra 8.7.11 community edition installation, which is pretty vanilla - meaning that there have been very few, if any modifications. I'm trying to block an entire domain and was able to after a couple of changes. Here are the relevant files ...

Re: If I am using postcreen, do I need to configure list of Client RBLs?

Thanks Phoenix. I did read your post about a newer method of blocking SPAM (rspamd), but it seems like quite alot of work to get it up and running and I would rather do it on a low volume or test server. The one that I am having issues with at the moment, is one of my primary customers, so I don't w...

Re: If I am using postcreen, do I need to configure list of Client RBLs?

Jorge, Thanks for your answer. That makes sense. So am I correct in thinking that the "Client RBLs" field under DNS checks in The Zimbra web administration panel under Global configuration \ MTA is actually part of the anti-spam / anti-virus service? Can you elaborate on the workflow there...

If I am using postcreen, do I need to configure list of Client RBLs?

We have used Client RBLs in the web administration panel for a few years now.

With 8.7, we can now use postscreen.

Should we remove the RBLs from the web admin panel once we have configured them in the postcreen configuration?

What happens if they are used together?

Any downsides?

Thanks,
David

<SOLVED> Unable to block an entire domain with Zimbra 8.7

I'm trying to block an entire domain in Zimbra 8.7 Community Edition. This is a pretty fresh install, so I should have any defaults that come with a zimbra installation. We are getting attacked by a Chinese domain called qq.com. The addresses are random each connection example 324125@qq.com, 351341@...

What is the difference between Zimbra Suite Plus and Zextras?

I've just noticed that the Zimbra Suite Plus modules exists. I found the WIKI article here: https://wiki.zimbra.com/wiki/Zimbra_Suite_Plus How this is different from Zextras? I note that the documentation pages which shows the module logos, say "powered by zextras" at the bottom of the eac...

Re: How change ownership of a shared address book.

Changing an account into a resource change the features embedded by it. No more ActiveSync for example. But you earn an account on the license. zmprov will allow you to delete or to add the objectClass you need to change your account into a calendar resource. If it's a shared address book, why woul...

DualBoot wrote:Maybe you should consider to change the account into a resource account.
You can do it by using command line and changing objectClass.


Do you have an example command or link to a zimbra wiki article on that?

What are the pros/cons of changing it into a resource account?
