Zimbra Forums

there should be more easy way for spam system to learn.
Something like forward SPAM mail to some spam@mydomain.com mail which will after that block all mails from the same sender.
fro example I forward mail from selling@xxxxxx.xxx to spam@mydomain.com and after that I will never get any mail anymore from selling@xxxxxxx.xxx

Now I need to manually edit file and adding spam mails to it.

There is currently a problem with zmtrainsa (i.i. it is not currently working) so it's not as effective as it should be and Zimbra are supposed to be working on a fix. This sort of block is trivial in rspamd, it consists of adding the domain to a config file (done via the rspamd ui).
