General DNS & Domains Dyn Email Update Clients

ISP blocks SMTP(25) port.

I want to host email server witH dynamic ip. i have already registered in dyndns. the problem is our ISP is blocking incoming SMTP (port:25). I have configured the routeR to accept the connection to port 200 and forward to internal server port 25. IT works fine. Now, I want a solution to forward all incoming mail to port 200 on my router which will take it to the internal SMTP server. Will SendLabs GATEWAY meet this requirement. remember mail has to be redirected to PORT-200.

Yes, but note that you must have your own domain and related DDNS hosting service to be able to use SendLabs Gateway. It does not work with a DynDNS hostname.

Yes, for your inbound email SendLabs Gateway will allow you to bypass the blocking of port 25, but you'll have to change your port to one it supports (it supports 24, 25, 587, 2525, 10025 and 52525). I'm not aware of any alternative product (from anybody) that allows you to use an arbitrary port.

Don't forget that to send email you'll need to relay it through another server.
