My mail server has a lot of spamtraps. They come from various sources, but one of the most prolific is bad addresses in personal domains. Several of my users have their own domains, such as my own johnlevine.com, in which they use a handful of addresses. Those addresses tend either to be people's first names, for individual mailboxes, or else the names of companies. If I did business with Verizon (which I do not) I might give them an address like email@example.com. All those domains get mail to lots of other addresses, which is 100% spam.The made up addresses are largely dictionary attacks, which is obvious when I see sequential spam to barry@, betsy@, and bruno@. Some of them are company addresses that leaked to spammers before the companies went out of business years ago. And some are just mysteries.
