hotmail doesn't accept my mail

sent from my server...

[xnavigator]

Hello,

I have a dedicated server. All email provider such as google,yahoo ecc accept the emails that I send from my server (php function mail())

Hotmail is only provider that dosen't accept my emails.. I don't know what should I do..

I have already tried to record my ip to [postmaster.live.com...]

but nothing is changed.. I have tried to insert a SPF record to my dns zone but no results...

anyone know what should i do? :(

thanks

Hi xnavigator,

Does your mail server IP have a reverse DNS entry? That's a common reason large hosts may flag/drop emails.

When you say hotmail doesn't accept the emails, do they refuse them completely, or put them into the user's junk mail folder?
