Blacklisting entire countries

[Thomas]

I´ve tried, but there seems to be no contact address, and the clostest thing
I could find where this comment would fit in is this newsgroup

I´m using Vista and the built in Windows Mail
I received a mail from a friend who has an account at Live Hotmail
I´ve got 3 mail accounts at 3 different mail providers, all pop3, and I´m
using all of them within Windows Mail
When I tried to answer that mail, my reply bounced back with a note, Hotmail
has put a block against my IP address, because of a complaint they received
from some user(s)
I tried all 3 mail accounts, always same result

M$ is obviously not aware that a growing amount of ISP´s (such as italian
Fastweb) does not provide public IP´s to their customers, but uses a giant
NAT to route entire cities or regions over the same public IP
Subsequent this means blocking any such IP equals blacklisting an entire
country
The consequence for me is, I cannot use Windows Mail anymore, but have go
through the web interface of my mail provider to send out mail, and that of
course works, because my mail provider is no source of spam, neither am I,
only the IP address my ISP uses for my town is blocked

Funny side effect, using Windows Mail you can´t even send mail from one Live
Hotmail account to another, as long as one of them is located in Italy

I donno, but when spam filtering at M$´s own mail server renders M$´s own
mail program useless, that might be a bit exaggerated

... and just in case someone from M$ reads this:
How about a contact address where one could report such a problem?

Mail providers like Hotmail do not block the IP address of individual users.
They block the IP address of any mail server used to send spam. Since
one mail server may service thousands of customers, the effect of black-
listing a mail server can be widespread. The theory behind this is that the
admin of the mail server is responsible for keeping spammers from using it.
Customers whose mail server is blocked frequently will seek out other,
(hopefully) less spam-friendly, providers. It also points out the need to have
diversity in one's available SMTP servers. In your case, you should consider
getting a free account with Gmail, which then could be used for sending
whenever your native SMTP server is blacklisted.

In this case, Hotmail must have blacklisted my IP (or better the IP my ISP
uses for all their customers in my town), my mail provider isn´t blacklisted
at all
If any of my mail providers was blacklisted, I would not be able to send the
very same mail from the very same account at the same mail provider to the
very same address by using my mail providers web interface
Furthermore, I also have a Hotmail account, which I rarely use
For a little test I´ve tried to send mail to and from my own Hotmail account
to and from my wifes Hotmail account and the result is the same
If I send the mail through my wifes Outlook Express on XP, same as my
Windows Mail on Vista it bounces (as if Hotmail has blacklisted itself)
If I log in at the Hotmail website and send it from there it goes through

I guess it couldn´t be any clearer which IP is on the blacklist here

The larger mail providers seldom use the same server to do both
SMTP and webmail. Webmail does not use port 25.

I guess you are not up to speed with the local news in Italy. Saw the short that CNN run concerning a local ISP in Italy. The Law confiscates many things when warranted even in Italy
