I need a script for my Debian-based server that can do the following: when a user want to download his e-mails he uses the following method to login to my server: POP3: server: mylinuxserverhost login: hislogin:hispassword@hisoriginalhost and with these data my server queries that third-party e-mail server and transmits the e-mails to the user who connected to my server. My server will check for viruses via ClamAV. So it has to use my postfix's filters. This is a gateway solution for corporate e-mails. I need the script and an easy to understand detailed guide how to install it on my server. Please only bid if you understand everything.
