Ask HN: How to Block Spam Mails? For my SaaS, a lot of fake accounts are created which seem to be automated bots from @mail.ru @bk.ru @list.ru etc domains. Now of course I could set up a manual block list or so, but I was wondering how you are doing it? Is there an existing service or at least a good block list that I can already use? Thanks! [Edited for clarity] |
Do you mean "I want to block incoming spam email to my email addresses" or "I operate an email mailing list and I want to block bots from joining the list" ?
What I did for now is:
- Added a honeypot field (invisible to users, but bots might fill it) -> if it's filled, instant reject - Added a check for spammy domains -> if it's from such a domain, instant reject
But I would guess that there will be new domains that I don't have in my blocklist and then I need to add them again and I would like to have this as a crowdsourced effort.
