Don't send mail directly from a dial-up IP.
Use your ISP to send mail.
A lot of the spam zombies are coming from dynamic IPs and it's just plain sense to reject any email coming directly from those IPs.
Sorry.. No sympathy. I'm using a dial-up connection with a dynamic IP on a ISP that has had spam problems and *never* get email rejected.
