Restric ammount of mail sent

Dear All,

Please, I have a question. Is it possible to restrict the ammount of emails that the accounts can send in a determined time?

What I mean is that, for example, any account can't send more than 10 mails in a minute.

Waiting for your comments,

Best,

Marco

Look into CBpolicyd. I've implemented it in 8.6 (and it runs well enough) but most recently I've read there may be issues with it in the 8.8.* series.

You could always use Rspamd for ratelimiting inbound and outbound email, it can also replace the current anti-spam solution in ZCS.

Hi Bill,

I was searching for something to this in the forum/wiki. However, I couldn't find anything that is why I wrote my question in here.

Thank you for your help and I will look for the implementation of the Rspamd.

Best,

Marco

Implementing Rspamd on a ZCS server is fairly easy, see the following thread and wiki article:

https://wiki.zimbra.com/wiki/Rspamd

I don't use ratelimiting on my server as it's only a small server but it should be trivial to get running, the documentation of the Rspamd web site is quite detailed: https://rspamd.com/doc/modules/ratelimit.html

Hi Bill,

Again thank you for your help. However, I was checking Rspamd is available for fedora and centos but not for Red Hat. Am I right?

Best,

Marco
