Please check this like this: http://www.howtoforge.com/faq/1_38_en.html

Also check if your server is listed on a spam blacklist. That might be the reason why other systems refuse the connection to your system.

I look this at http://www.nl.sorbs.net/lookup.shtml

Dynamic IP Space (LAN, Cable, DSL & Dial Ups)

Record Updated: Sun May 14 11:47:30 2006 GMT
Additional Information: Dynamic/Generic IP/rDNS address, use your ISPs mail server or get rDNS set to indicate static assignment.
Currently active and flagged to be published in DNS

but my ip is 85.55.8.* and Netblock: 85.52.0.0/14 (85.52.0.0-85.55.255.255) It's blocked my server ??

Yes, it's blocked, because it's in this range: 85.52.0.0-85.55.255.255.

The reason seems to be that you have a dynamic IP address.

Most blacklists block dynamic IP addresses.
You can use another email server for relaying your domains: http://www.howtoforge.com/forums/sho...ight=relayhost
