This is why folks use techniques like greylisting and why you should almost never use a catch-all mailbox. Spamhaus usually stops a big chunk of them too.

- toxik 6y agoHard disagree on catch all. A catch all allows you to trace who gave your address to spammers, and then to bin all email to that address.
- FullyFunctional 6y agoYep, I've been doing this for nearly a decade. This in combination with Gmail's spam filter works just fine. I have caught quite a few emails to my parents from people who can't spell their (simple) email address.
- bbarnett 6y agoYou don't need a catch all for that, just give unique email addresses to each, and edit /etc/aliases. NOTE: a few bits of info here, although someone mentioning ipchains means their comment is from an older time of course: - use ipset for large sets of blocked IP addresses. That's what it's for, and it works well without slowdown, even on massive sets - http://www.ipdeny.com/ipblocks/data/aggregated http://www.ipdeny.com/ipblocks/data/aggregated This is a nice list of IP addresses broken down by region. Handy do download weekly, or monthly, and then dump into ipset. - firehol is also a nice list to use, eg: https://raw.githubusercontent.com/ktsaou/blocklist-ipsets/master https://raw.githubusercontent.com/ktsaou/blocklist-ipsets/ma...
- jchook 6y agoExcept then spammers who send to [huge list of words]@your-domain.com all go to your inbox. It's much safer to use a regex pattern or generate forwarding emails ad hoc. Please contact me at f7m4 {at} proxyto.me if you have any interest in beta-testing an app that does this exact thing.
