Hi, i have been using perfect server for centos for many years, only problem I faced it blocking of my server because some email id getting affected and then virus sending tens of thousand emails in one go. which setup is best for implementing email rate limit? per hour per domain limit, per id limit, or whole domain limit. Please guide
Current ISPConfig setups use Rspamd as spam filter and Rspamd has a rate limit module, that you can use: https://rspamd.com/doc/modules/ratelimit.html
can you please point me to perfect server guide for centos? which one you suggest? centos new updates keep coming very frequently
