I would like to implement a more targeted fail2ban rule for a particular domain (and ALL its ever changing subdomains), but I don’t want the strictness of this rule (block 1st time) to apply to the other rules. To that end, I have the following questions:
- Can I install fail2ban on the same machine or will that mess up the built in netfilter in any way?
- Where exactly are the postfix logs stored? I can’t find them anywhere?
