Re: Email protection or what else ????

Hi,

I discovered something strange.

I have sendmail running with 3 or 4 different domain name I can send
email as foo@xxxxxx or foo@xxxxxx etc....

The email server seems to work fine.....

except, that there are some few domain like "Hotmail" where Any email
sent to somebody having a 'hotmail' email address, will never receive my
message
I will receive no message saying that there is a problem etc. Nothing
this is pure lost

I checked my IP and I am not blacklisted

I moved the server recently, ( => having another Fix IP address ) And I
noticed this problem again

- Any idea what could be the problem ? - Any idea how to solve it ?
- Should I be necessary whitelisted ?

You already asked this and had answers, yet you come back and
don't give any more data to help the group to help you, that won't do.

Maybe you didn't read your previous thread conclusion?
here it goes again:
---------
The problem is that some 'public' email provider like 'hotmail'... NEVER
accept my emails, even if I am not blacklisted !

That's another and different problem than 'greylisting', problem here is that
you seemed to believe that every MX used the same central and well known 'blacklist'
as you think that you are "not blacklisted".

Why? I suppose that
they have specific rules,

Most certainly.

which is a problem

Do you think, that there another reason ?

Well, there could be so many "reasons" ;-)
When that's the case I suppose you get a DSN with a reject code?
That'd be a good info to start with :-)

Please mind that I'm not the 'hotmail' mailmaster and you may get a
more precise answer about what kind of specific rules they used
on your mails if you try and contact the hotmail services.

Now, I reckon that's not necessarily easy nor even feasible to get
a technical contact with this kind of 'institutions' then you
may have some good old crystal ball advice here if you can post a
good sample of the DSN you get :-)
