Can you investigate the source of the leakage? No. Others have your e-mail address and you have no control of their systems or historical knowledge of their use of the address. You don't know, as a whole, where their address lists are kept and whether those have been compromised or not. You don't know if one of your friends was at a coffee shop and their traffic was being sniffed. You don't know all possible usages/occurrences of your e-mail address and over whose architecture that address went.
Let's say that you find out that Bob somehow wound up giving your e-mail address to a spammer. It doesn't matter whether it was deliberate or accidental - a spammer now has your e-mail address. Those lists are bought and sold between spammers and the only real variable is whether you have confirmed that your e-mail is read and acted upon or not. You have no control over the sale of these lists, and Bob does not either. Additionally: what would you do with Bob? Tell a friend to lose your e-mail address? Either way, that bell can't be un-rung.
.
in your address? (see "Gmail dots-dont-matter"). Are you asserting you've never sent or received email from this address? If you've ever sent or received from an address then someone else will have it... and from there it could be leaked - which is why I question the alleged "privacy" of your address. After all, the whole point of email is to be reachable.Are you using the "+suffix" feature or have any dots .
I do not use+
, but it has one dot.Are you asserting you've never sent or received email from this address?
Of course I used this email for mailing, but only to my private contacts and very rarely for business needs. Hence is my question: how to find out who screwed and leaked it :)could it be that any of your private contacts was compromised and thus your address leaked from there to spammers?
probably, but how to detect which one? My aim is not punish them, but to close the hole and prevent further leaks and spamming
