Honeypot detection

amaury1093 opened this issue · comments

Does email address under test hide a honeypot?

Is there a way to detect that address is a Honeypot?

tbh I don't have a clear idea how to do it either. But other email validation services provide it, so it could be good to investigate how they do it.

I guess it'll be based on some heuristics. An idea could also be to include in the binary a moderately-sized txt file with honeypot addresses.

Honeypots are like normal addresses, you can check that address is spam trap with sending one email and waiting for listing your ip/etc.. in blacklist OR you can have database of spamtraps, so just filter them out

waiting to being blacklisted seems bad idea...
