said by Ellen098:The ISP is Mediacom. I turned off the modem, router, & PC last night & left it off for over 16 hours. Unforunately, that didn't help. If the ISP is doing MAC binding, how do you suggest getting around that?
Also, when I send email from my PC, it goes through my ISP. That's when Spamcop blocks the IP address which seems to be static even though DHCP is enabled. But, when I send an email from my phone, using the same POP outgoing server but a completely different IP address, Spamcop does not block the email.
You can't change the IP since Mediacom uses static IP's. You'll either have to wait for the ip lease to be up so it switches or ask mediacom to change it(they most likely won't).
