Hello,

One of our new users has a problem with sending emails. His domain is brand new but every time he sends email Yahoo/Hotmail filter the email and mark it as spam.

The domain is brand new, the IP address he is on is not blacklisted. What could the problem be?
 
Is there any clues in the headers of the emails to tell you why they're being marked as spam? I haven't used hotmail/yahoo in many years so i can't remember what info gets revealed in the full headers but hopefully it's a bit like the spamassasin point scoring system.

Also you might find this useful http://help.directadmin.com/item.php?id=207

Maybe you need to check your mail spf records,
and setup how hotmail likes it:

here is the official link from microsoft about how to do it:

also the article below have got some very nice info about how to deal with hotmail spf stuff:

My dns have records like below. Hotmail seem to like my setup. You can try this in your domains also:

Under domain dns management:
Code: 
yourdomain.com.	TXT	"v=spf1 a mx ip4:11.22.33.44 ip4:12.13.14.15 mx:mail.yourdomain.com ?all"

change 11.22.33.44, 12.13.14.15 with your ips :)

I tried the Microsoft guide but I just received the same TXT records as I already have. So I tried yours and replaced the first IP with the primary nameserver IP and replaced the second IP with the secondary nameserver IP and replaced yourdomain with the domain.

I sent an email through roundcube and it got filtered by Hotmail. I now also tried from a different domain on the server it also got filtered. The IP address is not blacklisted, the TXT records you guys gave me do not make a difference. What could the problem be? This is really bugging me :(
