Hi,
I've used the excellent Mailbee.NET components to develop an email application.
One question: like everyone else, we get a lot of spam. In addition to implementing the SPAM filter (which I've done), I would like to add the ability for our application to BOUNCE unwanted spam back to the sender, indicating that an email address no longer exists.
Other programs like MAILWASHER do this and it's apparently quite effective in getting your email addresses removed from unwanted lists :-

Please can you tell me how I could implement a "Bounce Back" feature using the MAILBEE.NET components?
Many thanks,
Hedley Muscroft

I guess the most straightforward approach here is to create bouncemail message based on some widely-used template, and then send it over SMTP.
The problem here is you can't really tell whether actual sender address is supplied, in case of spam you're going to encounter a lot of fake sender addresses.

Thanks for your reply Igor.
Do you know where I can find a "bouncemail template"? I tried Googling and came up empty, but I might not be searching the right thing.
Thanks.

When referring to templates, I meant we all get bounceback messages from time to time, and though there's no common standard on bounce message, there's only a few popular formats. One of them, for example, has a subject:
Code:
| Mail delivery failed: returning message to sender |
|
|
and message text begins with:
Code:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
blahblah@blahblah.com
Unrouteable address
------ This is a copy of the message, including all the headers. ------
...
... |
|
|
You can use such a message as template for creating your own bouncemails.
