Hi there,
I’m running a small low-volume self-hosted mail server. Since my mail volume is
small, I’m considering setting up spamtraps to help train my spam filter. Is
this still effective? If so, are there any tips or short tutorials on seeding
spamtraps (i.e., getting the spamtrap address used by spammers)? I’ve done a
quick web search, but almost all of the hits are aimed at spammers trying to
avoid spamtraps.
Seeding traps to guard against your own platform;
1 RFC-2142
2 Seed traps onto your web pages.
Historically harvesting bots don't actually parse HTML,
putting them in comments is fine.
3 Put a garbage header into you outbound mail with trap addresses
Message-IDs might also work well, provided that M-IDs are a catchall
sub-domain.
4 Review your inbound logs for addresses that are currently being
rejected for unknown users.
... larger trap farms use other methods, but based on what you
presented, this should be fairly good.
