hotmail accepts mails but doesn't deliver them

can anyone knows how to configure postfix to successfully deliver e-mails to
hotmail account. My e-mails are accepted by their servers but do not get to
mailbox at all, or a treatet as spam.

It is just a matter of forwarding to your hotmail account. There might be a
blacklist on any hotmail account on your server?
Actually you should know this, but I am only thinking with you...

my server is not blacklisted and is configured well to all my knowlegde, of
course :)
It is general problem and has something to do with SenderId implemented by
Microsoft.
My question is if anybody had this problem and somehow found the solution
such as: configuration hacks and how should look the spf record and so on.
I would be very greatful if I got any clue!

You should be routing outgoing mail through your ISP's mail server (use
"relayhost" to do that). Many ISPs (probably including hotmail) won't
accept mail sent from an ISP's client IP range on the grounds that its
likely to be spam. I route all my outgoing mail this way and have never
had anything bounced by hotmail.

SPF isn't relevant here. Its purpose is solely to stop the backscatter
(rejections) that result from spammers sending spam to non-existent
mailboxes with your address forged as the sender.

I had serious problems with hotmail a couple of ears ago when one of
my clients wanted her mail forwarded to her hotmail account for a couple
of weeks, from a postfix server via the isp smarthost.
My test mails to check her .forward file were all bounced as " forwarded too
many times". I queried postmaster@hotmail, but am still (not) waiting
for a reply. We got her to set up a gmail account, no problem.

Check out http://postmaster.live.com/Services....enderSolutions

Specifically "Smart Network Data Services" at
https://postmaster.live.com/snds/index.aspx

By registering you show that you are accepting responsibility for mail
from your server.

I went through this procedure for both my office and home mail servers
and in both cases it fixed the problem.

AOL have a similar registration scheme as well but don't seem to be as
bad as M$ at ignoring standards.

Hotmail (Microsoft) uses the "Report spam" button on the Hotmail
application to determine how "spammy" your IP address is.
I run a bunch of Mailman lists for a relatively "not technical"
population. A fair number of them are too lazy and/or inept
to unsubscribe from mailing lists they're not interested in any more.
Instead, they use the report spam button. Hotmail apparently
doesn't take into account the fact they have been receiving
non-spam from the same IPA and MAIL FROM address for years.

Also, when a Hotmail user comes back from vacation and finds
5000 messages waiting, and three quarters are spam, they'll
mark it all spam to dump it all. These two behaviors keep
my Hotmail spam fraction hovering around 0.5% despite no
real spam actually making it through the lists.

The Hotmail service is "free" and "free email" users apparently
tolerate false positives. I have started advising these people
that if they want reliable email they have to go somewhere
reliable, but of course they don't want to hear it.

If Hotmail isn't delivering messages from your users, it could
be your IPA's spam fraction is too high.

You have to sign up for a Smart Network Data Services account with them.
It will only work if your domain appears in the reverse DNS (pointer record)
for the IPA you send from.
