You can still run your own MTA, just it should forward all outbound mail to the ISP MTA and not attempt any direct to MTA deliveries. If you have TLS setup and your ISP has TLS capabilities it will remained encryted the entire way, it will even remain encrypted if the recieving end has TLS too, if the recieving end doesnt then you dont loose anything cause your own MTA woudl have dropped it as well (the encryption that is). > And as for hiding. There's not much hiding involved. You need to rewrite the envelope if you do not have your own domain, if you do then you just need to make sure your MX is your MTA, simple. > Further more, > the ISP keeps logs (or atleast they SAY they do) of all the IP's > assigned via DHCP. They do and it is probably in radius logs, not DHCP, they are actually required to keep them for a period of time, I have the last 3 months here on the live filesystem and have ALL of them archived. I have had cases where the FBI or local SBI subpeonaed our records to find out what customer was on a certain IP address at a given time. > So there's not much hiding involved. You cannot hide from your ISP, they know who you are.... ;-) > Now, if 25 inbound was shut down (which I could see an > ISP doing) then I would seriously be in trouble because there'd be > no inbound email any longer. Why would an ISP shutdown port 25 inbound? I see no logical reason to do so, spam does not get delivered directly to a users desktop (at this time at least). The zombies are not controlled via port 25 inbound (at least any I have seen). In other words, I know of no good reason to shutdown port 25 inbound... now port 25 outbound, yes, definately for dynamic IP space.
