Re: [Dovecot] Getting more spam
Sadly, I have to take exception to the suggestions to "reply to spam with your contact address" and "sign up for free porn". By the loosest definitions, you are "asking" for spam when you do this. The other suggestions, posting to bugtraq and usenet, are excellent ideas. Also, An excellent way to get more spam is to unsubscribe from spam with the target address. This seems to work REALLY well. -ejay -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Neale Pickett Sent: Wednesday, March 21, 2007 4:53 PM To: dovecot@dovecot.org Cc: [EMAIL PROTECTED] Subject: Re: [Dovecot] Getting more spam On Wednesday 21 March 2007 2:01 pm, [EMAIL PROTECTED] wrote: > What is a a spam sink, can you redirect it via MX records?

What a crazy world. You're probably best off following Jay's suggestions. It won't take long for spam to start coming in. Another suggestion is to surf a lot of porn and sign up for as much "free porn" as you can. Not only do you get loads of spam, you also get to surf for porn and call it classwork! Neale

Post to usenet with some addresses from your server. Respond to a few spams listing your email address as the contact information. Remove all the spam filtering rejection rules from Postfix-- i.e. don't require FQDN for anything, use none of the RBLs, etc... Make a post or three to BugTraq. Post to Slashdot with an address from this domain. Click on popups (in a sandboxed environment-- no point in being stupid!) and give an address at that domain for contact info. This is what my users do, and then wonder why they get spam... -- Jay Request mortgage information, again with that email adress

Also, I am running a custom smtp proxy in front of postfix to log all SMTP transactions, and postfix is configured to be very lenient in terms of checking.
