It is also worth looking at MMDF, and PP. MMDF is designed with a modular style, i.e. one program to accept mail, one program to deliver it, one program per 'channel' to transform it as required. It was a pity that MMDF required filling in a license originally, whilst sendmail was free. If it had been the other way around I am sure that we would all be using MMDF. MMDF can be found in ftp.uu.net:/networking/mail/mmdf
