Mail Routing

[visionthing]

My ISP (comcast) blocks their ranges of DHCP addresses. The effects of this is that some of my emails (through my E2K server) do not reach some receipients because these address ranges are "blacklisted" by comcast. This is presumably to prevent spammers, but has a negative effect on legitimate users. I've read somewhere that ISP's (maybe comcast is among them)allow for email routing through their servers. I'm looking for "how to" advice on how to do this, if this is possible. As I've said, I'm using E2K, but I can't really see a place for this unless it's the "smarthost" area located on the default smtp servers properties-delivery-advanced area. If this is the place to do it, can someone explain how to do it?

Thanks for looking at this

The SmartHost are is indeed where you do this. You need to connect with the ISP's tech support to find out if they support this functionality on their servers.

By the way - it is quite possible that it is not ComCast that is blocking your address, but that it is the ISPs and/or recipient mail servers that are blocking ComCast's dynamic IP address range from sending the email.

Good luck!
