I would like to send automatically a notification to specific senders taht
their messages are not accepted. How can i do that with Outlook 2007 Vista
version?
Create a rule that sends back your message. Of course, since it can be seen
in the headers of your sent e-mail that it originated at your e-mail client
and NOT at your mail server, those recipients can see that you DID receive
their e-mail.
If you are attempting to send bogus NDR (non-delivery report) e-mails back
to spammers, even you know that spammers do not use their own true e-mail
address. They use a bogus one: no such domain, username doesn't exist at
the existing domain, or it points at a valid account at that domain (but it
isn't their account). The result is you waste resources at your mail server
for undeliverable bogus NDRs or you afflict an innocent with your bogus NDR.
Anyone that receives your bogus NDR can report it as spam to both your
e-mail provider and also the the public blacklists. Deliberately spewing
out e-mails (despite that they are bogus NDRs) that are unsolicited to the
innocents to which you spew them is SPAMMING!
Clean up the turds at your ends. Stop trying to toss them back out which
only ends up in the yards of innocents. Take 5 minutes to think through
what you are trying to do - and why it won't work. Some e-mail clients or
monitors also have a "bounce" feature but anyone receiving those bogus
bounces can see they did NOT come from your mail server (i.e., they can see
they were not rejections by a mail server).
The bounce feature in any e-mail client is very stupid and irresponsible
primarily because ignorant users will actually believe the software author
is providing an appropriate feature and that it will somehow it will avoid
further spam. Spammers do not use their own e-mail address. Instead they use
a bogus one (which may be a valid e-mail address for some user) or they use
one that they've already stolen and is often included in the recipient list
of e-mail addresses. Spammers change their e-mails every time they spew so
blocking on the one they used last time won't eliminate getting their crap
when they next spew. Spammers rely on the ignorance of e-mail users that
believe using blacklists and/or bouncing by the sender's claimed e-mail
address has any effect on reducing received spam.
- Blocking by the sender's e-mail will NOT eliminate spam in your mailbox.
The spammer's e-mail address changes at their will.
- Bouncing based on the return-path headers in an e-mail will NEVER hit the
spammer. Only boobs think the spammer will identify themself.
YOU are not connected during the mail session between the sending and
receiving mail servers so you have absolutely no means to guarantee of
knowing from the return-path headers (e.g., From or Reply-To) as to who sent
you. The sender can put anything they want in there. Even mail servers that
first accept a message, end the mail session with the sending mail host, and
then check afterward if the e-mail address is valid or not and then try to
send a *new* message back to the sender will get it wrong. If a valid IP
address of the sender is included in a Received header, that does NOT
provide you with an e-mail address to which you can bounce back their spam.
You cannot rely on the return-path headers to guarantee identifying the true
sender. These bounces are sent blind!
The spammer isn't going to identify themself to receive that bounce. Now
consider that only aren't you the receiving mail server but you are even
further removed from the mail session between the sending and receiving mail
hosts. There is nothing in your e-mail client that can absolutely guarantee
who is the sender of the spam you got in your Inbox, so bouncing it anywhere
means wasting bandwidth for you to send the bounce, disk space and
bandwidtch by your mail server to attempt to deliver your bounce, disk space
and CPU cycles for the receiving mail host to accept your bogus bounce mail,
and some innocent getting slapped with your misdirected bounce (which, by
the way, can be reported to blacklists as backscatter and get you
blacklisted).
Think about it for all of 10 seconds, if even that long. Would you like to
be the victim of a "mail bombing" because some spammer usurped your e-mail
address, sends out a million copies of their crap with you identified as the
sender, and then all those boobs using e-mail clients with a bounce option
end up filling your mailbox with all their misdirected bounces?
Any e-mail client that provides a bounce option are irresponsible software
authors. Ignorant users sending misdirected bounces are irresponsible
e-mail users. Have a read at:

Warning: If you send me backscatter, like misdirected bounces which to me
are unsolicited and hence spam, I will report you to blacklists, like at
SpamCop, for your irresponsible and ignorant use of flawed anti-spam
schemes. If you punish me with your backscatter, I will punish you! I'm not
the only one with this attitude. There are plenty of spam reporters out
there and they will report you, too. It is not up to the rest of us to
placate your sensitivity for your spam problem by being your victim. Get a
responsible anti-spam solution.
