I am not a spammer...  But I think my email address has been placed on a spam list or black list.  My
website has an autoresponder that will automatically email visitors
after they have entered their information at my website, and my theory
is that people have reported my email as spam when in fact they are
the ones who submitted their email address at my website.  Anyway, HOW
UNBLACKLISTED? (I'm having trouble emailing some of my customers)

Hi zukajuice-ga,

First of all, what makes you think that your email address has been
placed on a blacklist? Have you had emails bouncing back to you? If
so, do they point you to a specific source or tell you that you are
listed on a blacklist?

The reason that I ask is that most blacklists block IP addresses or
mail servers, NOT individual email addresses. Since your email address
is MSN, I'm assuming this is not the problem in your situation. Please
check your returned emails (are you receiving these) and look for
error messages. If you do not understand the error messages, then
please post one here under a request for clarification and I'll see if
I can help you further.

FYI, the largest anti-spam blacklist on the Net (and the one which
most anti-spam software programs subscribe to is the MAPS RBL
(Realtime Blackhole List):

Another potential problem is that you may not be using MSN's SMTP
server when sending outgoing mail. If you're using a different
outgoing email server certain ISPs map block any email from your
account (this helps to prevent spam abuse from people who use other
people's email addresses to send spam).

Your outgoing mail field should be set to:

If you're using Outlook or Outlook Express to check your email you
should also have the "My server requires authentication" box selected.

I hope this helps to answer your problem. If it does not, please post
a request for clarification with additional information on exactly
what is happening when you send mail that doesn't arrive at its
intended destination.

Thank you for using Google Answers!

Thanks for the informative reply although I'm not quite clear on
everything you suggested.  Here is the responce back I'm receiving,
and any additional insite you may have would be greatly appreciated.
(keep in mind, this is not happening with every email I'm sending.  I
can send email to most of my contacts)

Hell again zukajuice-ga,

A 550 access denied error usually means that the mail is being
rejected from a site where a reverse DNS lookup fails. It sounds like
you may need to reconfigure your outgoing SMTP server settings like I
mentioned in my previous email. This wouldn't happen with all email
addresses, because not all email servers check to see if your outgoing
email domain matches your SMTP server domain. Therefore, your first
step should be to make sure that your outgoing email server is set for  (see this step in instructions below).

MSN recently started to upgrade their email servers in an anti-spam
effort. If you are using Outlook Express then you need to check/change
your settings. Here are the instructions:

Go to Start > Programs > Outlook Express  

2. Click on Tools > Accounts  

3. Highlight MSN Mail by clicking on it  

4. Click on Properties  

5. Click on the Servers tab  

6. Make sure that your outgoing mail server is set to
"" Then click on the checkbox under Outgoing Mail
Server that reads "My server requires authentication"

7. Click on Settings  

8. Click on the circle for Log on Using  

9. In the Account Name box enter your MSN e-mail address 

10. In the Password box enter your password  

11. If you wish you can click in the Remember password box  

12. Click on the checkbox beside Log on using Secure Password

13. Click on OK  

14. Click on OK  

15. Click on Close  

If you are using Outlook, MSN Explorer or some other email client then
let me know.

Hope this helps! If not, please post a request for clarification.

Allow me to expand the question.

Someone told me today that according to his Mail Washer Pro  4.0 the
domain is blacklisted for email.

I would like to find out HOW this can be verified:
1. I can send and receive email from this domain
2. Installed Mail Washer Pro  4.0 but this did not give any results,
not even a warning

I have done many searches and they all refer with technical
explanations to the service providers, etc.

I manage this domain and it is hosted on the servers of
