You should be routing outgoing mail through your ISP's mail server (use
"relayhost" to do that). Many ISPs (probably including hotmail) won't
accept mail sent from an ISP's client IP range on the grounds that its
likely to be spam. I route all my outgoing mail this way and have never
had anything bounced by hotmail.

SPF isn't relevant here. Its purpose is solely to stop the backscatter
(rejections) that result from spammers sending spam to non-existent
mailboxes with your address forged as the sender.
