Should i bounce spam

That is what led me to you…I typed revenge on scammers. That is quite some selection :- he he he just noticed these responses were written 8 years ago.

Just a note…… Mailwasher will NOT work with yahoo mail…… yahoo mail does not allow bouncing of emails even if using a program such as mailwasher. I have tried both Mailwasher, and BounceBully and neither of them will work with a yahoo mail email account, even if you use outlook with it.

I really wish it did,. Mailwasher works great! We used it at my former employer , we used to recieve spams a day. After about weeks it got whittled down to spams a day. After a couple months we were consistantly getting only average a day. Thanks for the tip. This might be useful to finally get rid of all those spams from Ticketmaster.

If anyone has not yet bought tickets from them, my advice is to use a throw-away email address because they put you on a list without asking and they do not honor unsubscribe requests. Thanks Ray. Actually, I need this program for my bitchy Ex who keeps sending my messages. Thanks Raymond for the info. So, to fight Spam, we need to be aware of the tricks used by Spammers. Thanks again!!! Like Richrd say ,you have a very nice site and I appreciate your hard work!

Thx for the Thread! Jeff 10 months ago. HAL Admin 1 year ago. JB 1 year ago. TJ 8 months ago. Michael 1 year ago. It was easy to find what I was looking for. I could easily scan a help article to find the information I needed. The help articles are easy to read. The help articles helped me resolve my issue. Mailchimp is easy to use.

I just love Mailchimp! The help articles don't make sense. I wish there was a video that showed me how to do this. What I'm trying to do in Mailchimp doesn't work the way I think it should. It was hard to find what I was looking for. I never found what I was looking for at all. I have to contact Support to resolve my issue for example, an account or billing problem. When you send messages, the bounce address is signed, and when you receive bounces, any message that does not have a correct signature is rejected.

If you enforce BATV for incoming messages, and you are not using the outgoing filter to sign your bounce address, then all incoming bounces will be rejected, including legitimate ones. If you enable BATV for outgoing messages, and you are not using the incoming filter to enforce BATV, then you will gain no advantage, and may have trouble receiving legitimate bounces at the destination server that handles your incoming mail.

Catchall Domains If you have configured your email system to accept all email sent to any address example. And it's not all good news, see this note for details. Second, there have been some changes to the RFCs, and a couple of the items deal specifically with spam filtering and bounces.

The key change from the point of view of this web site is that rejection "bounce" messages SHOULD NOT be sent unless the receiving site is confident that those messages will be usefully delivered. Bounces for spam, viruses and a few other unwanted messages will NOT be usefully delivered since they won't go back to the source. Rejections are fine. See Bouncing vs. Rejecting for more details. This page is primarily intended for people who run mail servers that receive email for multiple users.

Individuals who get their email through an ISP or company server normally won't have much control over what needs to be done to solve this problem. There are a few positive things that end users can do though. They can certainly help put pressure on their email admins if something needs to be fixed. In many cases it's just a matter of the people in charge not realizing how things have changed since about the beginning of And if they haven't adjusted, the mail server may have ended up on blacklists.

If so your email could be blocked from at least some sites. End users should never use a program to bounce spam in hopes of abusing the spammer or getting removed from spam mailing lists. Spammers will never see those fake bounces, they'll go to an innocent person who may report the bouncer for sending them spam. It's also not a good idea to try and retaliate against spammers in any way other than reporting the spam you receive, there's far too much potential for abuse of innocent third parties.

Anyone who wants to refer someone to this page is welcome to do so. If the goal is educate someone on the evils of bouncing spam so that they'll modify their servers actions, please be sure that you're notifying the right person. Please use caution, not cluing someone in is probably preferable to irritating the wrong person who may already be doing it right. Lately I've been getting a lot of bounced spam.

And of course I didn't send any of the spam, so I report as many as possible as spam, which they are to me. See note 1 Even before the volume got out of control, I got tired of typing out emails and filling in contact forms explaining why the sender of the bounces shouldn't do that, so I created this site. The information on this page comes from knowledge I've gathered in years of dealing with computers and poking around the internet and newsgroups, as well as my own experiences dealing with spammers.

I received some suggestions and corrections from people far more knowledgeable than I am. And I've done my best to verify that everything here is accurate, but it's up to you to make sure that it's appropriate for your situation. And of course, at some point this information will be outdated.

The internet is a constantly changing medium. Some changes are for the better, some for the worse. Unfortunately spammers have forced several of these changes, and now they're forcing another one. My goal is to provide information that will convince more people that bouncing spam is a bad idea.

The same reasoning applies to bouncing viruses found in incoming email. Anyone who thinks it would help is welcome to send a link to this page to anyone who has sent them bounce spam.

Please make sure that they really are the source though, spammers also forge bounces. It might even have been me who sent you the link, although anyone who wants to is certainly welcome to do the same. If you are responsible for any of the above you should seriously consider fixing your system. There are people getting thousands of bounces etc.

As of the beginning of the operator of TQMcube. And he said that his lists were being used to filter about million emails per day. You do not want to be there. And his list isn't the only one you could end up on. Spamcop now allows backscatter bounces to be reported as spam, and once there are enough reports, they also add the server to their blacklists.

Most blacklists that add backscatter sources will result in blocking all email from that server. But now www. That list can be used to reject just unwanted NDNs. There's a big difference between rejecting email and bouncing email. Rejecting email is the acceptable way of handling undeliverable email, bouncing email is the one that is causing problems. Rejecting is done during the SMTP transfer when the sending and receiving servers are talking to each other.

If the receiving server rejects an incoming email, then the only one who will get the rejection is the sending server. If it's a legitimate email that server should notify their local sender with a failure report. See RFC for details. If it's spam then the sending server is probably a bot, and it's not likely to be listening. Rejections can be temporary a 4xx code, like mail box busy or permanent a 5xx code like no such user. A great deal of spam would disappear forever if it was simply rejected during the SMTP transaction when no such user is appropriate.

Bouncing is done after the receiving server accepts the email and the connection with the sender is closed. So the email has to be sent somewhere instead of simply rejected. The only way to determine where to send it at this point is to look in the headers, normally the From or the Return Path.

If your server is bouncing spam you will eventually get listed as a spam source. The way it should work is that the sender sends an email to their mail server. That server contacts the recipient's server, which determines whether or not the email should be accepted. If it's rejected, the sending server gets that notification before closing the SMTP connection, and it's then the responsibility of that server to notify the original sender.

Ideally, bounces should only be sent to local recipients, not to someone on another server since you can't guarantee the validity of the headers. A receiving server should be very cautious about notifying the original sender directly, servers should usually only provide notifications to their own users. Apparently the main purpose was to clarify some of the statements.

But there are several changes which apply specifically to spam filtering and Mail Rejection. In RFC Section 4. Section 6. While it discusses the importance of delivering any message that can be delivered, it recognizes the problems that can be caused by unsolicited messages:. Rejections are still fine and preferred] since that will only involve the originating server [or spam bot].

And in the case of a false positive, the originating server can still notify the sender. But do not bounce spam or viruses. Once an email has been passed on to the recipient's server, there is no longer a safe way to automatically notify the sender of problems.

Spammers have changed the way that they send spam, and this is forcing a change in the way that email is handled. It used to be A Good Thing to return email if it couldn't be delivered for any reason. Personally, up until a couple of years ago I was adamant that in my opinion all undeliverable email needed to be returned. Whether it was a bounce or a rejection didn't make a lot of difference at that time. That way the sender was notified that there was a problem and they could take steps to fix it.

This worked fine as long as the vast majority of email was legitimate and had valid headers. But spammers are ruining that. Estimates on the amount of spam vs. But it gets worse. That's just the raw numbers. Your mail servers have to be able to handle that volume increase. And now that a single spammer can send millions of emails or more in a day, all with forged From addresses, it's counter productive to return all the undeliverable emails.

Sometimes those forged addresses belong to someone. I can guarantee that they don't belong to the spammer, so someone else is going to get the bounces. I know of people who have gotten 10s of thousands of bogus bounces a day while some spammer was doing a big run with their address.

Usually it's just coincidence, but it can also be malicious if someone has irritated a spammer and they're performing a Joe Job. Any server that is the source of backscatter becomes a source of internet abuse.
