I hadn't thought about fetching failures. I wanted the whole thing to be lightweight because it should run on a 300MHz Pentium II with limited RAM. On top of that I wanted to avoid a complex postfix setup because I don't have a lot of experience in configuring it. Postfix will have to do 3 different tasks: receive mail from fetchmail and transmit it to amavis, receive scanned mail by amavis and store it in MailDir, and transmit outgoing mail to the ISP mail server. If postfix stores mail in the MailDir format there is no need for procmail but I will have to teach it to store mail from different accounts to one single place. I will have to add some RAM to the machine and study the postfix documentation a bit more. Thanks for your answers!
