You'll be in a lot more trouble if you ignore the failure messages.

You may not want to be a spammer but if you ignore failure messages you look like one.

So if you really want the entire 'net to eventually block you, here's how:

Simply don't use a working email address. Of course your emails will be blocked by a lot of mailserver admins (including me) for not using a resolvable sender, but that's okay.

Years ago I walked away from a $10,000 contract to build a mailserver that could do this for large quantities of email.

If you really want to do this there are many of ways to route incoming emails to /dev/null. While I'm not going to go into detail on how to look like a spammer, perhaps someone else will reply with more detailed information.

To expand on what Jeff said, it will look bad for you if you do this. Your entire server has a high likelyhood of being flagged as spamming server if you block everything, so we won't recommend this.

In any case, more details would be:

1) Remove the pop account completely, you don't need it. The script you're using will specify the "From" value in it's headers.

2) Create a forwarder as the name of the from/reply value, and set it as a :blackhole:, if you're sending from [email protected], you'd create a forwarder:

sender  ->   :blackhole:

which will accept all emails from anyone who sends to it.. and happy delete them. The senders will not know they're being deleted. You won't know what's being deleted.

Note, if anyone is emailing you to request to be removed from the list and you fail to actually remove them, in most countries, you're at risk of being fined quite heavily (there are laws in place for this). If they can't reply, be sure to provide a link for un-subscribing from your list that actually works.

So bottom line, we don't recommend this. Keeping an open line of communication is usually a good thing, especially when some may see your actions as illegitimate (in fairness, the context of your emails were not disclosed, so this could be presumptuous, or not)

Could be a troll... Every forum I use, I normally see them!

That said, I had a new user this week, paid for a month, spammed from his account 2hr into activation, I suspended him in time...... Joys of offering cheap hosting I suppose, and if we put our services at a high price, hardly no-one would choose us... Can't win!

And we have a client who sends more emails in a day than you'd probably see in a lifetime. A major organization, well-known. If I disclosed the name you'd know you've heard of them.

All legitimate email to a good and very large optin customer-base list.

Running on their own server. Using a customized setup (their own people built it).

A good customer.

I used to be in the mailing list business (almost ten years ago) and that's how I met these folks. As well as the other one; the guy I walked away from.

The return emails are automatically filtered through a script that removes them from the list.

Yes there are legit bulk mail senders..... I fight the fight from the good side often for one of my e commerce customers... he sends newsletters etc to his customer base of 10k+. I often have to battle to keep him off of the spam list.

So there are good ones.... but like anything the bad ones come to mind first.

Sorry guys.. I'm not a spammer. I have my own server and i m sending a research centers daily newsletter to ppl who wants to have it only..
I sent my mails with an smtp script cuz my customers usually 60-70 years old academicians and they have no idea what the hell is a "junk mail folder". so i need a pop3 account.

thanks for your helps for now. i'll keep fallowing this thread if any more idea comes..

Maybe some of the email addresses you send to do not exist anymore? Hence the failed bounce messages.

@eker:

Please reread post #2 in this thread. I never said you were a spammer. I said that if you ignore failures you WILL end up looking like a spammer, your IP#s will be blocked, you'll have problems with your outbound connectivity provider.

You should be using a script (both free and commercial scripts are available) that will automatically accept bounces and remove them from your list.

If you don't, you'll end up on spamblocking lists. And most of your email will no longer get through.

I already told you how to do it. And I already advised you to not do it.

The decision is yours.
