Emails not reaching hotmail.

[prale]

I installed dovecot and went back to RC3.
(Because I want to update to RC4 safe )

Also I created a valid SPF record for one of my domains, at the lycos DNS manager.

Still no succes with hotmail.
But gmail and others work fine :S

By the way, how can I use the built-in bind dns server?
I tested with creating only a NS record at lycos, then the site is down. It also needs an A record with the server ip to work.
