Mail arrives in SPAM on Yahoo

[alecksievici]

The problem is pretty simple: when i send an email from my server (from any domain) to yahoo, it gets flagged as spam. Any other server (gmail or any other free email provider) receives the mails in inbox.

Until a few days ago i thought this was becuase my ip wasn't properly configured by my internet provider (when looking up the hostname on my ip i was receiving blowfish.from.swordfish), but now it works ok.

I've set up my hostname and the hosts file to match the lookup, i edited postfix's main.cf to also match the lookup and still it doesn't work.

Could this be an issue from ispcp, my postfix configuration or just yahoo's problem?

PS: i used http://www.isp-control.net/documentation...l_problems and everything looks ok...

i really need help because it's driving me crazy :-W
