Your log format seems to be broken. Check `rspamadm configdump logging` - there are likely some extra tabs or other garbage.

I think it's quite clear that no generic purposes spam filter can deal with spam in all languages all over the world out of the box. You need to customise both Rspamd and SA for your particular environment. Both Rspamd and SA have similar techniques to filter spam (Rspamd can even use SA rules). The...

As Rspamd author, I claim that all posts from 10424bofh regarding Rspamd are totally invalid and toxic, therefore they should NOT be considered if you want to setup Rspamd.

Well, it is quite common that if you do strange things you get strange results. First of all, Rspamd is not SA and you should not expect it to work as SA. Why do you need to relearn the existing messages so often? It is trivial to check mtime and do not use not updated files by a simple `find` pipel...

DNS sockets pool is fine. It is used as a tradeoff between security and source port randomization and performance (do not open a socket on each request). This pool is slowly rotated over time. Here are the default settings: % rspamadm configdump options.dns *** Section options.dns *** timeout = 1.0;...

1. More context switches means that Rspamd spends more time in waiting for results than on processing them. It is not an issue for all modern 64 bit platforms, e.g. Linux. 2. Rspamd uses pool of sockets to query DNS for better performance. It does not use TCP sockets at all for DNS so it is quite st...

Please let me know if you have any integration issues. Once Zimbra is able to work with Rspamd I can also add the corresponding information to the Rspamd documentation.
