Perhaps you should consider outsourcing your email -

Greetings,


Let me explain the situation and see if I can get anyone to tell me how they are handling it.


We are offering wholesale dialup ports. When a user connects he is authenticated and can do whatever

it is he/she wants to do on the net. Unfortuantely some have decided that they will relay spam off of other servers.


To address this i have proposed installing filters that will only allow these folks to connect to

port 25 of the ISP that has bought the ports. This way they are not able to relay off of anyone elses machine

that is using port 25 and the buyer of the ports should have the correct measures set up to prevent bulk mail from

going out.


Will this be sufficient, providing that the server they are allowed to connect to has set up his mail server to 
prevent massmailing..?


Suggestions/comments?
