i have a fixed ip and business internet to my house. $120/mo run my own email on an old mac mini. its great because i was able to set up spam folders in all accounts. they drop in the spam and it goes to a folder in my account. the subject gets the source ip and domain added to it. any server i don't recognize gets dragged to another folder and bam! that ip is blocked. love it!
