Hello,

I seen, that here are some microsoft mail admins. So I try this once
more bevore I give up with microsoft at all.

I have a private mail server in hetzner network (5.9.7.51). This server
is well managed and only my mails and a few others are routed over them.
I can assure that no spam is coming from them (or accepted there).

The SPF record is in place and current. There is no dkim and there will
be no dkim in near future. However, the TLS is in a DANE record and the
domains (most of them) secured by DNSSEC.

I have one friend who have emails on hotmail. Getting mails from him (as
well as many spams from hotmail and live.com) is routed fine to my
domain(s). But when I try to reply, the mail is bouncing back with the
non saying message
   550 SC-001 (COL004-MC3F22) Unfortunately, messages from 5.9.7.51 weren't 
sent. Please contact your Internet service provider since part of their network 
is on our block list. You can also refer your provider to 
http://mail.live.com/mail/troubleshooting.aspx#errors.

I tried to contact [email protected] but even that mail bounced
back and was not accepted by microsoft even that this is the only mail
address that must not bounce in any cases by RFC.

So I have no way to contact microsoft about that issue. And microsoft is
the only provider, that has such a badly managed system.

I can assure that my server is not on any known lists and microsoft is
really the only one that makes this troubles. And the mails I send are
pure text mails with PGP signature.

So, if someone from microsoft reads here, you might have a look into
your logs. On private (not on the list) I can even provide you with logs
or the account on hotmail.com (live.com). But please use a address that
is accepting mails.

When I discussed that issue on swinog mailing list, I got many answers
that this is known about microsoft and some of the replies (and even my
answers) was not nice about microsoft and mail. But keep that beside if
possible and hopefully the issue can be solved here.

Regards
   Klaus

Ps. I will not go to a javascript overloaded page in the web that does
    not do or add any usefull thinks. For my understanding, for mail
    related stuff, postmaster@domain is the main contact for such thinks
    (or abuse@..., but this is not standarised).
