Project mention: DigitalOcean blocks SMTP ports 465 and 587 since last month | news.ycombinator.com | 2025-04-09
Not a whole lot of a source to share, sorry.
Whenever registering/subscribing to some provider, I always use a new,unique email address. If/when that provider gets their user database leaked, after some time, spam starts rushing in. At that point, I change my email address in provider's records, and old one is moved to "spamtrap" alias on my server. Over the years, quite a few has accumulated - linkedin, yahoo, you name it...
Fail2ban [0] parses mail server logs, and I have a rule there, where source IP address of anything incoming to spamtrap, is looked up in whois and logged. Then, manual awk/grep/sort contraption is run periodically.
DO's AS14061 used to be consistently in top-3 spam sources, occasionally taking #1 spot.
