Hi everybody.
As I have posted quite a few times, I get very few spam e-mails, never more than four a day, and more often than not none at all. I have always put this down to using Spamgourmet disposable addresses for signing up to forums, newsgroups, etc. and using Mailwasher to "bounce back" the few I do get. I have also used E-Prompter to check mail on the server, and occasionally delete it using this program.
However, about a month ago I removed Mailwasher and E-Prompter from my PC and downloaded Simon's recommendation, "PopTray". After just a few weeks of checking waiting mail and deleting spam on the server with PopTray, spam has dried up completely - I haven't had any at all for about eight days now.
As a result, I have reached the conclusion that using Mailwasher and E-Prompter actually caused me to get some spam, albeit very little. I suspect that by using Mailwasher to "bounce back" mail, rather than making spammers think the address doesn't exist anymore, actually lets them know that the address is active, although I haven't worked out how, yet. I expect they could find out by checking the message source of a bounced back e-mail, but could they be bothered? Furthermore, I suspect than E-Prompter harvests addresses set up in it and passes them on.
I know this might seem a bit far fetched, but it seems too much to be a mere coincidence that since I dropped the previous programs for PopTray I get no spam at all.
