There are three possible solutions to this problem. 1. You can contact the ISP that is rejecting your mail based on the IP designation as dynamic space and ask them to stop doing that. IMO, that is very unlikely to work. For each responsible person like yourself running a secure mail server on a secure OS, there are 200 Windows machines that have either been exploited already or are waiting to be exploited and turned into spam spewing zombie machines. 2. You can smart host through an ISP server or pay someone to allow you to relay through their server. This is the likeliest solution. 3. You can buy a domain, get DNS server for the domain and setup Sender Policy Framework records that get updated with your dynamic IP address and hope that the ISP currently rejecting your mail will implement it and allow that to override the dynamic space blocklist that they currently use. I wouldn't count on this solution currently, but it is MUCH more likely to work in a year or so from now. Of course, the converse is that you are much less likely to be able to operate your own mail server a year from now unless you own a domain and control dns records for that domain. -- Bryan Phinney
