Re: Writing A Remailer
Hi all. I want to try to write a re-mailer that will run on my ISP's UNIX shell account. I am familiar with Windows socket programming (C/C++) but have never done anything in the UNIX environment.
Developing these things is actually eaiser to do in UNIX than Windows. I guess it depends on where you wish to being. Do you wish to write a remailer from scratch, or do you wish to just run a remailer? In either case, take a look at what other people have done, one site I like is ftp.hacktic.nl, there is source for a number of remailers there, among other things. You could compile that, and see what you like and dislike about a given remailer, and then adjust the code appropriatly. Most are written in C, so if you know C, you won't have very many problems. One thing to note, UNIX privilages, you would want to run your remailer as a deamon, a constantly running program(similar to a DOS TSR or NT Service). I am not sure if your ISP gives you enough access to run deamons. Good Luck Michael Peponis

I think you would also be able to use Procmail and Formail (two UNIX mail processing programs) to set up a quick and dirty remailer. Procmail could be set to look at the headers of a message for something like a header of "Remail-To:", or [REMAIL] in the Subject: header. If it finds this, it would use Formail to replace the headers with generic information, put the specified address into the To: field, and send the message on its way. I don't really know if you'd be able to set this up for chaining remailers or not though.

I have several useful FAQ's and documents available.
