We have a Linux SMTP server. We are facing that our email is sent directly to hotmails junk inbox.

- maildomain: @bloc.no
- smtp: smtp1.bloc.no
- SPF Record is created
- Reverse IP

We know the problem is not related to the content or header in the email.
We know the smtp is not blacklisted.

Anyone?

How can you know it is not a problem of the content or header? Hotmail's anti-spam algorithms and measures sre not discosed publically. So we can only guess here. I suspect hotmail also has large IP lists that for example give every server from russia a bad rating, at least we had them classified many business email from a russian customer that could not find any explanation as the mails were no spam, the smtp was no relay or blacklisted. So generally they very probably already give your mail a bad spam rating when your IP/Domain is not from the US i think.

If you have some friend who is running a bluecoat you can try sending him a mail and asking for the sender rating which is rather based on global traffic/behaviour rules of senders. For example if your domain has never sent a mail before or just a few and you suddenly send out a newsletter to 50.000 customers you immediately get a "suspicious" rating.

About content - usually if its a proper business letter in english language you will not have problems. But due to poor/idiotic intelligence of the spam keyword dictionary you sometimes get really bad ratings if its for example in another language there might be totally correct words that however contain part of an english language "spam word". Other cases i have seen was a bank and the reason the mails got classified as junk was they were about "loans", which is a quite normal topic for a bank, but also a common word in spam mails. Yet another example was a business email that had important stock information and one of the medical companies listed unfortunately also appears in many spam mails about products to enhance your manhood. There are many more examples when a proper mind would tell "This is a 100% clean mail" and some spam filter will tell "its spam".

So unless you get an official comment from hotmail you really can't tell. And it is really unlikely as i know hotmail/msn you will get a usable comment.

i meant ironport, not bluecoat of course. Well i was currently working at that appliance, so i was a bit off in my mind when i wrote bluecoat. Ironport mail gateway has quite an intelligent spam rating and you can see the rating a mail gets as an admin. Maybe that could give a good overview if there is "generally" a problem that may let the mail appear like spam?
